Changzhou Jiayuan Chemical: Fluorochemical Raw Material Prices Continue to Rise, Cost Pressure Transmits Along the Supply Chain

Recently, under the combined influence of price fluctuations in upstream basic raw materials such as fluorspar and sulfuric acid, changes in the international supply pattern, and recovering downstream demand, prices of several products in the fluorochemical industry have remained at elevated levels. According to industry monitoring data, the May tender price for anhydrous hydrogen fluoride saw a significant increase, while the hexafluoropropylene (HFP) (https://www.jy-chemical.com/hexafluoropropylene-product/) market continued to experience high-level volatility, with the mainstream transaction range also moving upward.International Supply Tightens, Strong Cost SupportFrom a global perspective, the supply of fluorochemical raw materials is facing new uncertainties. On the one hand, geopolitical factors have led to unstable production at certain overseas mining sites, coupled with a significant downward revision in production guidance by major Australian lithium miners and tightened lithium ore export quotas by Zimbabwe, which have pushed up production costs for lithium carbonate and downstream lithium fluoride (https://www.jy-chemical.com/lithium-fluoride-product/). On the other hand, maintenance or production cuts at some overseas fluorochemical facilities have affected international trade flows of products such as HFP and polyvinylidene fluoride, further exacerbating the periodic tightness in domestic raw material supply.Looking at the upstream of the Chinese industrial chain, although the fluorspar (https://www.jy-chemical.com/fluorite-block-fluorite-ball-product/market) shows regional divergence due to mine resumption and imported arrivals, the average price level remains relatively stable. The sulfuric acid market maintains a high-level stalemate, supported by rising raw material sulfur prices, supply tightening, and recovering downstream demand. Multiple Products Follow the Price Increase, Obvious Market Linkage EffectAffected by these factors, the fluoropolymer sector has also shown linkage. HFP, a key monomer for fluoroelastomers, fluoroplastics, and fluorinated ion-exchange membranes, continues to see its price move upward. Producers have been tentatively raising their offers, and the market transaction center of gravity has steadily shifted higher. In addition, the price of battery-grade lithium fluoride has recently risen significantly, and the market quotation for lithium hexafluorophosphate has also increased, reflecting both the sustained release of demand in the new energy sector and the transmission effect of a tightening global lithium resource supply chain.Market Outlook: Cost-Driven and Demand Recovery in ParallelIn the short term, the weak supply-demand pattern in the fluorspar market is unlikely to see significant improvement. However, with cost support and loss recovery, the upward trend for hydrogen fluoride is expected to continue. On the international front, attention should be paid to the impact of geopolitical conflicts on maritime logistics, energy costs, and export policies for key raw materials.Against this backdrop, supply chain stability has become a key concern for downstream enterprises. Relying on a complete fluorochemical industrial chain layout, Changzhou Jiayuan Chemical maintains stable supply across multiple product lines, including inorganic fluorine products, organic fluorine products, and fluorinated intermediates, providing customers with reliable product quality and professional technical services, and helping downstream enterprises navigate the challenges posed by raw material fluctuations and changes in the international market.

Its main applications are concentrated in three core industries: microelectronics, healthcare, and refrigeration. These applications are based on its chemical stability, non‑flammability, low toxicity, and specific physical properties (e.g., low boiling point, ultrasound contrast capability). The following sections provide a detailed description of its uses, end‑use industries, and the properties that enable them.1. Microelectronics Industry – Core use in chip manufacturingThe microelectronics industry is the largest consumer of octafluoropropane (https://www.jy-chemical.com/octafluoropropane-product/), accounting for more than 60% of global consumption. The key properties exploited are its chemical stability, low reactivity, and excellent plasma etching performance.1.1 Plasma etchantUse: Fine etching of integrated circuits (ICs) and semiconductor chips (including 5nm and below process nodes), especially for patterning materials such as silicon, silicon dioxide (SiO₂), and silicon nitride (Si₃N₄).Properties leveraged: High chemical inertness: in plasma state it reacts only with target materials (e.g., silicon) without corroding other chip structures, reducing process defects. The fluorine radicals (F·) generated during decomposition have moderate activity, providing controllable etch rates and enabling nanoscale precision for fine structures such as transistor gates and interconnect lines.1.2 Device surface cleaning agentUse: Removal of residual photoresist, metal contaminants (e.g., copper, aluminium), and polymer residues generated during chip manufacturing.Properties leveraged: Insoluble in water but volatile, so no additional drying step is needed after cleaning, avoiding moisture‑induced oxidation damage to chips. Low toxicity and no reaction with chip materials (e.g., metal electrodes, insulating layers), thus no new impurities are introduced.Application scenario: Precision cleaning processes in semiconductor assembly and testing (packaging). The most important medical use of octafluoropropane is as an intraocular gas tamponade after vitrectomy, mainly to assist retinal reattachment and promote macular hole healing. It utilises its chemical stability, good biocompatibility, and controllable absorption to create a stable environment for ocular tissue repair. A typical example is given below. 2. Medical applications – Adjuvant treatment for rhegmatogenous retinal detachment (RRD)Rhegmatogenous retinal detachment is a common ophthalmic emergency, where the neurosensory retina separates from the retinal pigment epithelium. Without timely treatment it can lead to blindness. Octafluoropropane plays a critical role as an “intraocular support” in such surgeries:Treatment principle: After vitrectomy to remove haemorrhage and proliferative membranes from the vitreous cavity, octafluoropropane gas at a concentration of approximately 18‑20% is injected into the eye. The gas expands inside the eye and tamponades the retinal break (especially those located in the mid‑peripheral or inferior retina), pressing the retina back against the pigment epithelium. At the same time it blocks the flow of subretinal fluid, giving the edges of the break time for cell proliferation and adhesion repair.Key advantages: Compared to air (intraocular residence time 1‑3 days), octafluoropropane has a longer absorption period (about 1‑2 weeks), providing longer‑lasting tamponade and reducing the risk of post‑operative redetachment. Its chemical stability means it does not react with ocular tissues (e.g., lens, iris), and the incidence of post‑operative complications (such as accelerated cataract progression) is lower than with other long‑acting gases (e.g., sulphur hexafluoride).Clinical operational details: After surgery, patients must maintain a specific head position (e.g., face‑down if the break is located inferiorly) to ensure that the gas continues to tamponade the break. The gas is gradually absorbed over 1‑2 weeks; after retinal reattachment, no second surgery is required to remove it.Continued in the next chapter

[ Jiayuan Rare Gas Monthly Review ] : Helium Rose Steadily in April, Expected to Fluctuate Upward in May (April 2026)

1. Market AnalysisThe monthly average price of bottled helium increased during this period. Geopolitical risks in the Middle East continued with no clear signs of improvement. Under Russia’s helium export controls, the supply shortage in China’s helium market intensified, leading to rapidly rising market prices, with transactions concentrated on the higher end. In April, bottled helium sales went relatively smoothly – channels actively took delivery in the first half of the month, while some channels began to release partial stock for profit in the second half, resulting in active market trading sentiment and an upward shift in the transaction center of gravity. The supply shortage persisted in the East China region, where channels were mostly reluctant to sell, making it somewhat difficult for downstream users to source product. The Southwest region also actively followed the price uptrend.The average price of both imported and domestic tube‑trailer high‑purity helium (https://www.jy-chemical.com/helium-product/) increased during this period. Due to uncertainty over the magnitude and duration of supply tightening, many players actively built inventories, and market supply gradually moved toward a tight situation. Imported helium led the price increase, with domestic helium actively following suit, leading to rapid price gains. According to statistics as of April 28, both the monthly average price of imported tube‑trailer high‑purity helium and that of domestic tube‑trailer high‑purity helium rose. Market trading sentiment was good, and enterprises mainly focused on active shipment.Xenon market prices were stable, but the transaction center of gravity moved downward, and the monthly average price declined, remaining flat month‑on‑month. The oversupply situation in the xenon market has not yet changed, with major producers holding high inventories, leading to an obvious decline in market prices.Krypton market prices were stable, but the transaction center of gravity moved downward. Downstream buying interest was mediocre, and enterprises mainly sold at low prices.Neon market prices were stable, but the transaction center of gravity moved downward. With ample channel inventory in the neon market, trading sentiment was relatively poor, and prices remained stable at low levels. 2. Market OutlookHelium market prices are expected to increase in May 2026. The impact of the Middle East conflict is expected to persist in May. Russian helium export controls are expected to see some easing. The market is anticipated to show a trend of initially falling and then rising. Domestic tube‑trailer helium prices are expected to rise. The overall supply tightening situation in the market is unlikely to improve. The anticipated easing of Russian controls in the short term can only alleviate the supply tightness to some extent, but it will hardly reverse the overall situation. As supply tightness evolves, the market is expected to return to its main upward trend.Xenon market prices are expected to decline further in May, due to weak downstream buying support.China krypton market prices still have room to decline in May, as enterprises face increasing delivery pressure amid high channel inventories.Neon market prices are expected to decline in May. In the short term, market trading sentiment is relatively weak.3.

Industry development history and current situationAnalysis on the development history and current status of high purity boron trifluoride industryAs a key material in semiconductor manufacturing and new energy fields, the development of high-purity boron trifluoride is closely linked to domestic industrial upgrading and technological innovation. In the early days, due to technical barriers, the production technology of high-purity boron trifluoride was mainly controlled by developed countries such as Europe and the United States, and domestic companies were highly dependent on imports. This situation seriously restricted the development speed and quality of related industries.Starting stage: technology dependence and import challengesAt this stage, domestic enterprises are faced with the dual dilemma of technological blockade and market squeeze. Due to the lack of independent production technology, the domestic production of high-purity boron trifluoride is limited and it is difficult to meet the growing market demand. At the same time, high import costs and supply chain uncertainties also increase industrial risks. This situation has forced domestic enterprises to begin exploring the path of technology introduction and independent research and development in order to break the technological blockade and achieve domestic substitution.Technology introduction and independent research and development: an ice-breaking journey.With the country's strong support for strategic emerging industries such as semiconductors and new energy, the demand for the localization of high-purity boron trifluoride has become increasingly urgent. Domestic enterprises have actively introduced advanced foreign production technology and management experience, while increasing investment in independent research and development, and are committed to breaking through technical bottlenecks. Through continuous technical research and industry-university-research cooperation, domestic enterprises have made significant progress in the production process, equipment transformation, quality control, etc. of high-purity boron trifluoride, and gradually narrowed the gap with the international advanced level.Rapid development period: industry rise and intensified competitionIn recent years, driven by both technological progress and market demand, the domestic high-purity boron trifluoride industry has entered a rapid development stage. The rapid development of downstream industries such as semiconductors and solar cells has led to a rapid growth in demand for high-purity boron trifluoride: domestic companies have continuously improved their production scale, product quality, cost control, and other aspects, and their market competitiveness has been significantly enhanced. During this period, a group of companies with core competitiveness have emerged in the industry, and they have occupied a place in the market with advanced technology, high-quality products and efficient services.Current situation: The market scale continues to expand and the competition pattern begins to emergeAt present, the domestic high-purity boron trifluoride market continues to expand, and market demand is growing steadily. With the rapid development of downstream industries and the acceleration of domestic substitution, the market size is expected to maintain a rapid growth trend in the next few years. In terms of technical level, domestic companies have already possessed production capabilities comparable to those of international advanced companies, and their product quality and stability have been widely recognized. At the same time, the competitive landscape within the industry has also taken shape, with a few leading companies dominating the market, but other companies are also constantly catching up and surpassing, and market competition is becoming increasingly fierce.After the difficult exploration in the initial stage, the domestic high-purity boron trifluoride industry has entered a track of rapid development. In the future, with the continuous deepening of technological innovation and the continuous growth of market demand, the industry is expected to usher in a broader development prospect.3. Analysis of the industry chain structureWhen deeply discussing the high-purity boron trifluoride industry chain, we need to conduct a comprehensive analysis from upstream raw materials, midstream production links to downstream application fields. Upstream raw materials, as the foundation of the industry chain, are mainly composed of key substances such as borax and hydrogen fluoride. The price fluctuations of these raw materials affect the cost structure of the entire industry chain like a tide. Especially in the production of high-purity boron trifluoride, the cost sensitivity is extremely high. Any slight price change may cause a significant change in production costs. The midstream production link is the core area of technology intensiveness. From raw material processing to synthesis reaction, to purification and separation and filling and packaging, each step needs to be precisely controlled to ensure the purity and quality of the product. This process not only requires high-precision equipment support, but also relies on strict production process and environmental control standards. The establishment of technical thresholds is not only a test of the strength of the enterprise, but also the key to ensuring product quality and maintaining the healthy development of the industry.As for downstream application areas, high-purity boron trifluoride has shown a wide range of uses and huge market potential. In the field of semiconductor manufacturing, as an indispensable etching gas, it is directly involved in the fine process of chip manufacturing, and plays an irreplaceable role in improving chip performance and promoting the upgrading of the semiconductor industry. In many fields such as electronic materials, new energy, medicine and chemical synthesis, high-purity boron trifluoride also plays a key role and has become an important force in promoting technological progress and innovation in related industries.The various links in the high-purity boron trifluoride industry chain are closely connected, forming a complex and sophisticated ecosystem. In this system, the collaborative cooperation and technological innovation of each link are the key to promoting the sustainable development of the entire industry chain.

Boron-10 isotope technology breakthrough: production process innovation and broad application prospects

【Introduction】Recently, the Shanghai Institute of Applied Physics of the Chinese Academy of Sciences, in collaboration with a number of universities and enterprises, has made a major breakthrough in the efficient purification and large-scale production of boron-10 isotope (¹⁰B). This progress has not only promoted the technological upgrading of traditional fields such as nuclear energy and medicine, but also provided key material support for emerging industries such as semiconductors and new energy. The industrialization wave of boron-10 technology is sweeping the world .1. Technology and process: from laboratory to scaleBoron-10 is a rare isotope with an abundance of only about 20% in natural boron. Due to its unique neutron absorption ability, it has become a core component of nuclear reactor control rods and radiation shielding materials. However, the traditional purification process is costly and inefficient, which has long restricted its large-scale application.1. Gas Centrifuge UpgradeThe research team optimized the boron trifluoride (BF 3 ) gas centrifugal separation process and used a new composite material drum to increase the single separation efficiency by 30% while reducing energy consumption. According to Professor Wang Hua, the project leader, "The new process can make the abundance of boron-10 isotope reach more than 99.9%, and the purity meets the requirements of nuclear grade applications." The picture is a real shot of Jiayuan factory. Reproduction is prohibited. 2. Exploration of green technologyIn order to reduce chemical waste, new technologies such as electrolytic reduction and laser isotope separation have entered the trial stage. The Tsinghua University team used ionic liquids to electrolyze borates and initially achieved low-energy purification, which may subvert the existing production model in the future.2. Application scenarios: From "cornerstone of nuclear energy" to "anti-cancer weapon"With the maturity of purification technology, the application boundaries of boron-10 continue to expand, becoming a "star material" for cross-innovation in multiple fields.1. Nuclear Energy Safety and Generation IV ReactorsIn the fourth-generation nuclear energy systems such as high-temperature gas-cooled reactors and molten salt reactors, boron carbide ceramics containing boron-10 are used as core materials for control rods. A Chinese nuclear power company revealed that the use of domestic boron-10 components has improved the neutron economy of reactors by 15% and reduced annual operation and maintenance costs by hundreds of millions of yuan.2. Precision cancer treatment (BNCT technology)Boron neutron capture therapy (BNCT) uses boron-10 to target and aggregate tumor cells, and releases high-energy particles through neutron irradiation to accurately kill cancer. In 2023, China's first BNCT clinical center was built in Xiamen, and it has significant effects in treating gliomas, melanomas, etc. Experts predict that with the approval of domestic boron-10 drugs, the cost of treatment is expected to drop from 300,000 yuan per course of treatment to less than 100,000 yuan.3. Semiconductors and Neutron DetectionIn the semiconductor field, boron-10 doping can improve the radiation resistance of silicon carbide power devices; its high-sensitivity neutron response characteristics are also used in nuclear power plant radiation monitoring and customs anti-terrorism detection equipment.4. Deep space exploration and energy storage materialsBoron-10-based composite materials have been incorporated into the shielding layer design of China's deep space probes due to their light weight and high radiation resistance; in addition, their potential in new borohydride hydrogen storage materials has also attracted the attention of academia.3. Challenges and the Future: Cost, Standards and Global CompetitionDespite its promise, boron-10 technology faces challenges:High production cost : The price of 99% pure boron-10 has increased , and further cost reduction is needed;Lack of standards : The lack of unified purity standards in the fields of medicine and nuclear energy restricts market promotion;International competition intensifies : The United States, Russia, Japan and other countries are accelerating their layout, and China needs to strengthen collaborative innovation in the industrial chain.In response to this, the National Isotope Engineering Technology Research Center proposed a "three-step" strategy: to achieve localization of key equipment by 2025, to build a 10,000-ton deep processing base for boron products by 2030, and to take the lead in formulating international standards.[Conclusion] From nuclear power plants to operating tables, from space to laboratories, the innovation of boron-10 technology is quietly changing the landscape of multiple industries. With China's continuous breakthroughs in purification technology and application research and development, this "small element" may become the key driving force behind the "heavy weapons of a great power". In the future, how to balance technological autonomy and global cooperation will determine China's final position in this high-tech competition.
