【 Jiayuan Chemical 】Rare Gas Market Monthly Review: Increased Helium Supply Pressures Prices, Krypton-Xenon Market Stabilizes (August 2026)

Market AnalysisIn August 2026, the domestic rare gas market showed a divergent trend. Among them, the supply of high-purity helium continued to increase, and with limited recovery in downstream demand, the market had ample supply and prices were under pressure. After previous adjustments, the markets for products such as krypton and xenon tended to stabilize, with end-user procurement still mainly based on actual demand.Regarding high-purity helium, the market supply is relatively abundant due to increased domestic supply capacity and stable imported sources. Meanwhile, although sectors such as semiconductors, medical devices, scientific research, and fiber optic manufacturing maintain a certain level of rigid demand, downstream companies are adopting more cautious procurement strategies, mostly using a just-in-time purchasing model, resulting in insufficient motivation for concentrated restocking in the short term. Therefore, trading activity in the helium market has decreased, and market prices have entered a period of adjustment.From an application perspective, helium, as an irreplaceable strategic rare gas, is widely used in semiconductor manufacturing, cryogenic superconductivity, nuclear magnetic resonance equipment, aerospace, fiber optic production, and scientific research and testing. With the continued development of advanced manufacturing industries, the long-term demand for high-purity helium remains, but market competition is gradually shifting from resource supply to product purity, stable supply capacity, and comprehensive service capabilities.The xenon market remained relatively stable overall in August. Due to increased supply in the previous period, market inventory pressure persisted, and end-users maintained a cautious purchasing attitude, with market transactions driven by actual demand. Xenon is mainly used in high-intensity discharge lamps, medical lighting, aerospace propulsion systems, semiconductor etching, and scientific research. High-end applications place higher demands on product purity and stable supply.The overall krypton market remained relatively stable. Driven by demand from downstream sectors such as display panels, semiconductors, lasers, and specialty lighting, the market maintained a certain level of procurement demand. Currently, end-users are paying more attention to supply stability and product quality, and procurement is becoming more rational, resulting in a generally stable market.The neon gas market remained stable overall, with ample supply. Neon gas is primarily used in semiconductor lithography, lasers, and display technology. With the development of advanced manufacturing industries, high-purity neon gas will continue to have long-term application value. Currently, market transactions are mainly driven by immediate needs, and the overall market remains stable.Market OutlookEntering September 2026, the rare gas market is expected to continue to show a structural adjustment trend.Regarding high-purity helium, the supply side will remain stable, with domestic capacity expansion and imported resources continuing to improve market supply capacity. However, from the demand side, while industries such as semiconductors and medical devices have long-term growth potential, short-term procurement will primarily focus on cautious restocking, and market prices are expected to remain in a state of adjustment. As high-end manufacturing continues to advance, the future focus of competition in the high-purity helium market will gradually shift to supply security, product quality, and customized service capabilities.The xenon market will still face pressure to balance supply and demand in the short term, but as demand from high-end lighting, medical equipment, semiconductor manufacturing and scientific research gradually recovers, the market is expected to gradually return to stability.The krypton and neon markets are expected to remain relatively stable. With the continued development of the semiconductor industry chain, the demand for high-purity rare gases in lithography, laser, and electronic manufacturing will continue to be supported. In the future, high purification, domestic production, and stable supply capabilities will become key areas of competition for rare gas companies.As a professional supplier of fluorochemicals and specialty gases, Changzhou Jiayuan Chemical Co., Ltd. continuously monitors changes in the global rare gas market, providing customers with high-purity helium, krypton, xenon, neon, and other rare gas products and related supply services.

Leveraging its mature fluorochemical industry chain resources and product supply capabilities, Jiayuan Chemical continuously focuses on the application and development of high-purity fluorine materials in advanced manufacturing, providing global customers with a variety of high-quality fluoride products, including high-purity calcium fluoride. In recent years, with the rapid development of semiconductor manufacturing, precision optics, laser technology, and high-end testing equipment, 99.99% high-purity calcium fluoride (CaF₂) is becoming an important basic material in the advanced manufacturing industry chain. Compared to ordinary industrial-grade calcium fluoride, high-purity calcium fluoride places higher demands on impurity control, material stability, and optical performance, and its application areas are gradually expanding from traditional industries to high-value fields such as semiconductors, optoelectronics, and high-end optics. Why do the semiconductor and optics industries require 99.99% high-purity calcium fluoride?In the semiconductor manufacturing process, photolithography determines the precision of chip manufacturing, and the optical system in photolithography equipment requires special materials that can stably transmit high-energy, short-wavelength light sources.Calcium fluoride has a wide range of light transmittance, especially in the ultraviolet (UV) and deep ultraviolet (DUV) bands, where it has excellent transmittance. It also has low refractive index, low dispersion, high resistance to laser damage, and good chemical stability. Therefore, it has become an important material for high-end optical components and can be used in key components such as lenses, windows, prisms, and beam splitters in lithography equipment.For semiconductor devices, ordinary purity calcium fluoride is insufficient. Trace impurities, such as metal ions like iron, copper, and nickel, as well as internal crystal defects, can all lead to:Increased ultraviolet light absorption reduces photolithography exposure efficiency;Decreased optical transmittance affects chip manufacturing precision;Damage occurs during long-term laser operation;Decreased crystal stability shortens equipment lifespan.Therefore, calcium fluoride with a purity of over 99.99% improves material uniformity by reducing impurity content, enabling it to meet the stringent performance requirements of precision optical and semiconductor equipment. High-end optical-grade calcium fluoride typically requires further control over crystal uniformity, birefringence, and internal defects.Which customers primarily purchase 99.99% calcium fluoride?Currently, customers purchasing high-purity calcium fluoride mainly focus on the following areas:1.

【Jiayuan Chemical】A delegation from the Qiannan Prefecture Government Office in Shanghai visited Jiayuan Chemical to discuss new opportunities for comprehensive utilization of fluorine resources and c

On August 21, a delegation from the Qiannan Prefecture's Shanghai Office visited Changzhou Jiayuan Chemical Co., Ltd. They held in-depth discussions on the comprehensive utilization of fluorine resources in Qiannan Prefecture, the extension of the fluorine chemical industry chain, the development of new energy materials, and investment cooperation. Representatives from Jiayuan Chemical and its foreign trade team participated in the meeting. Both sides focused on how to leverage the advantages of fluorine resources associated with phosphate mines in Qiannan Prefecture, enhance the comprehensive utilization value of fluorine resources, and promote the implementation of high-value-added fluorine chemical projects.Leveraging the advantages of phosphate rock resources, further enhance the comprehensive utilization value of associated fluorine.At the exchange meeting, the investment promotion team from the Qiannan Prefecture Office in Shanghai introduced the local industrial base and key investment areas.Qiannan Prefecture possesses abundant phosphate resources and has established a relatively complete phosphate chemical industry base. Currently, the proven phosphate reserves in the area are approximately 5 billion tons, with fluorine as a byproduct of about 3.5% of the phosphate rock. Significant phosphate chemical industry clusters have already formed in areas such as Fuquan and Weng'an. Meanwhile, the infrastructure of chemical industrial parks such as the Weng'an Economic Development Zone and the Qiannan High-tech Zone is continuously improving, providing favorable conditions for the further development of the phosphate chemical, fluorine chemical, and new energy industries.From the perspective of the industrial chain, fluorine associated with phosphate rock is not only a by-product resource, but also one of the important raw material sources for the development of the fluorochemical industry.In the current phosphate chemical production process, if the associated fluorine is mainly used for primary recovery and basic fluorochemical products, its industrial value has not been fully realized. How to further improve the comprehensive recovery and deep processing of fluorine resources, and extend the associated fluorine in phosphate rock from a basic raw material to high-value-added fluorine-containing products, has become a key area of focus for the development of the fluorochemical industry in Qiannan Prefecture.This also became an important starting point for the exchange between the two sides. Extending the industrial chain from "fluorine recovery" to "fluorine utilization"During the meeting, both sides focused on exchanging views regarding the subsequent utilization of fluorine resources in Qiannan Prefecture.The region has already established a certain foundation in the fluorochemical industry, with several related enterprises. Anhydrous hydrogen fluoride and electronic-grade hydrofluoric acid have both achieved industrial-scale production capacity. However, in terms of industrial structure, some products are still mainly used as basic raw materials and exported, while there is still considerable room for expansion in downstream high-value-added fluorine-containing products.Therefore, improving the comprehensive utilization level of fluorine resources should not only focus on "how much fluorine has been recovered", but also on what products the recovered fluorine ultimately forms, what markets it enters, and how much industrial added value it can create.Based on this idea, the two parties explored the possibility of extending from phosphate rock-associated fluorine resources to fine fluorochemicals, new energy fluorine materials, and high-value-added fluorine-containing intermediates.According to the current investment promotion plan of Qiannan Prefecture, the local government hopes to focus on introducing fine chemical projects such as fluorine-containing pharmaceuticals and pesticide intermediates to fill the gaps in the existing industrial chain; in the new energy sector, the focus is on fluorine-based electrolyte materials such as lithium hexafluorophosphate and lithium difluorosulfonyl imide , to further synergize with the local iron phosphate, lithium iron phosphate and future solid-state sodium battery industries.Jiayuan Fluorochemical's industrial chain is highly complementary to Qiannan's resource advantages.As a company that has long been deeply involved in the fluorochemical field, Jiayuan Chemical's products now cover multiple fluorochemical sectors, including fluorite basic raw materials, organic fluorine, inorganic fluorine, electronic specialty gases, nuclear industry supporting materials, and pharmaceutical and pesticide intermediates, and it continues to expand into overseas markets.During this exchange, both parties agreed that there is significant complementarity between Jiayuan Chemical's existing business layout and the industrial base of Qiannan Prefecture.On the raw material side , the abundant phosphate rock and associated fluorine resources in Qiannan Prefecture can serve as an important fluorine source in addition to traditional fluorite resources, providing new raw material guarantees for subsequent fluorochemical projects.On the industrial side , Qiannan Prefecture has already formed industrial clusters such as phosphorus chemicals and new energy materials. If it further develops fluorine-containing intermediates and new energy fluorine materials, it can achieve closer synergy between the phosphorus, fluorine and new energy industries.On the market side , Jiayuan Chemical has long been deeply involved in overseas markets and has accumulated considerable experience in international customer development and export channels. This experience can provide opportunities for cooperation in further expanding related products in Russia, Central Asia, and other overseas markets. The meeting minutes also clearly stated that Jiayuan will leverage its overseas channel advantages to provide export matching services for local phosphorus and fluorine chemical companies.High value-added projects may become the focus of investment promotion in Qiannan fluorochemical industry.Based on the geographical location, raw material conditions, and current industrial status of Qiannan Prefecture, both parties believe that the future development focus of the local fluorochemical industry should not be simply to replicate basic production capacity, but rather to focus more on high value-added, technology-driven, and refined products .Especially in the fields of fluorine-containing pharmaceutical and pesticide intermediates, new energy electrolyte materials, electronic chemicals, and some fine fluorine chemical products, the products have a high unit value and a low proportion of transportation costs, making them more suitable for forming a complementary relationship with local phosphate rock associated fluorine resources and existing basic chemical industries.Both sides also exchanged views on the industrial cluster layout, and believed that if the phosphorus chemical, fluorine chemical and new energy-related enterprises could form a closer industrial chain collaboration within the park, it would help reduce the cross-regional transportation of raw materials, improve resource utilization efficiency, and further reduce overall production costs.From investment promotion and exchange to industrial cooperationThe visit of the investment promotion team from the Qiannan Prefecture Office in Shanghai has laid a solid foundation for both sides to further understand each other's industrial advantages.Next, both sides plan to continue communication regarding project inspections, industrial resource matching, and market channel cooperation. According to the exchange arrangements, the Qiannan Prefecture investment promotion team will also organize relevant fluorochemical companies from Jiangsu Province to conduct on-site inspections in the area to further understand the associated fluorine resources of phosphate mines, the conditions of the chemical industrial park, and the supporting industrial facilities.For Jiayuan Chemical, this exchange was not only a project matchmaking event, but also an opportunity to re-examine the value of fluorine associated with phosphate rock from the perspective of the industrial chain.In the future, Jiayuan Chemical will continue to leverage its advantages in fluorochemical product systems, industrial chain resources, and overseas market channels , actively explore more possibilities with resource-based regions in areas such as technological cooperation, product development, cooperative production, and market expansion, and jointly promote the upgrading of fluorine resources from basic utilization to refined and high-value-added utilization, creating new cooperation space for the high-quality development of China's fluorochemical industry chain.
