In July 2026 China's domestic rare gas market presented divergent trends Helium prices maintained a downward trend as sustained supply expansion significantly eased previous supply shortages while xenon krypton and neon saw varying declines in transaction prices amid weak downstream demand with strong wait-and-see sentiment prevailing across the whole market
Helium Increased Supply Alleviates Shortage and Puts Downward Pressure on Prices
In July domestic helium supply achieved remarkable growth On the one hand imported helium arrived continuously and stably On the other hand a large domestic helium extraction project reached full capacity to further expand domestic supply With rising supply but insufficient downstream demand the long-standing helium shortage was greatly relieved and bottled helium prices kept fallingIn the bottled helium market overall transaction prices declined throughout the month with weak downstream intake and slow trading pace Bulk tube-trailer helium also faced downward price pressure At the early stage of the month concentrated arrival of imported helium plus stable output from domestic extraction plants pulled prices down In the middle of the month market wait-and-see sentiment intensified and transactions slowed with prices stabilizing temporarily At the late stage of the month continuous release of domestic helium paired with sluggish downstream purchasing pushed prices down again Factory quotations of tube-trailer high-purity helium from major producing regions such as Inner Mongolia and Shaanxi have dropped to relatively low levels with thin trading volume and widespread caution among downstream buyers
Xenon Persistent Supply-Demand Imbalance Leads to Weak Market Prices
The average market price of xenon decreased in July with lower mainstream transaction prices The supply-demand imbalance of xenon has not improved Major manufacturers maintain high inventory levels which keep market prices falling Downstream purchasing activity remains sluggish and sporadic transactions are concluded at low price ranges The xenon market will still face heavy downward pressure in the short term
Krypton Conservative Downstream Procurement Low-Price Transactions Prevail
The average market price of krypton remained flat in July while actual transaction prices moved down End customers only replenish inventory as required with highly conservative procurement strategies Manufacturers and distributors generally adopt low-price sales to compete for orders and accelerate inventory clearance under the current market atmosphere
Neon Sufficient Channel Inventories Result in Sluggish Market Transactions
The average market price of neon stayed stable in July with a slight drop in mainstream transaction prices Distribution channels hold abundant inventories leading to inactive trading Manufacturers and traders mostly sell products at prices close to production costs
Maket Outlook Helium Price Declines to Narrow Xenon and Krypton Still Under Downward Pressure
Looking forward to August high-purity helium prices are expected to fluctuate with limited space for sharp declines On the supply side imported helium volumes will stay generally stable yet uncertainties exist in export license approval and ocean transportation cycles Domestic helium production capacity will continue to release to supplement domestic circulation supply On the cost side high overseas import costs offer support for imported helium prices while domestic helium quotations are already close to production costs so manufacturers have little willingness to cut prices further On the demand side rigid demand from medical and semiconductor industries still exists yet downstream purchasers remain prudent without large-scale centralized restocking Overall helium prices will slip slightly in August with a narrower decline range compared with JulyFor xenon prices are expected to keep falling in August due to sluggish downstream purchasing leaving room for further price declines For krypton prices will maintain a downward trend in August as weak end-user demand prompts market participants to clear inventories at low prices to recover funds For neon the market will stay steady in August with dull short-term trading activity

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. Companies in the semiconductor equipment and lithography industry chainMainly used for:Optical components for DUV lithography equipment;Semiconductor testing equipment;Precision exposure system;Laser processing equipment.With the continuous development of fields such as artificial intelligence, high-performance computing, automotive electronics, and advanced packaging, the global demand for high-performance chips is growing, which places higher demands on semiconductor manufacturing equipment and key materials, and the demand for high-purity optical materials is also increasing.2. Optical lens and precision instrument manufacturing enterprisesinclude:Ultraviolet optical lens manufacturers;Infrared optical equipment companies;Microscope and spectrometer manufacturer;Research institutions.Calcium fluoride can cover a wide spectral range from deep ultraviolet to infrared, and therefore it is widely used in high-end lenses, window materials, analytical instruments and other fields.3. Laser equipment companiesHigh-power laser systems have extremely high requirements for window materials, which must possess the following properties:High light transmittance;High thermal stability;High resistance to laser damage.99.99% calcium fluoride can reduce energy loss during laser operation and improve equipment stability.4.

【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.
