Jiayuan High-Purity Hexafluoroisopropanol (HFIP) Targets Semiconductor and New Energy Industries

Jiayuan supplies 3N hexafluoroisopropanol (HFIP, CAS 920-66-1) with a purity ≥99.9%. 3N HFIP is not only a common solvent in pharmaceutical synthesis and polymer analysis, but it also unlocks high-end applications that industrial-grade HFIP (99.0%–99.5%) cannot reach. In advanced semiconductor processes and lithium-ion battery electrolytes, even trace impurities can cause a precipitous drop in performance, making 3N-grade HFIP an irreplaceable key material.   The watershed of 3N purityResidual fluorides, moisture, and metal ions in industrial-grade HFIP can interfere with precision manufacturing. Industry data shows that a purity of 99.95% to 99.99% is required to meet electronic-grade standards for photoresist cleaning of chips below 3 nanometers. 3N (≥99.9%) is a basic threshold for entering the semiconductor supply chain, and Jiayuan can provide batch-level testing data on metal ions, moisture, and fluorides to support certification. Special Application 1: Precision Cleaning of SemiconductorsHFIP has a boiling point of only 58.6°C (far lower than IPA's 82.4°C) and is non-flammable, eliminating the risk of combustion and explosion associated with traditional IPA cleaning. Early patents documented that wafers could be cleaned and dried simply by placing them in HFIP vapor, leaving no residue on the surface. The unique feature of Jiayuan's 3N grade lies in impurity control: photoresist residue cleaning requires the solvent not to introduce new metal ions or particles. Fluorides and moisture in low-purity products can cause surface defects, while the 3N grade uses processes such as molecular sieve membrane separation to reduce impurities to the ppb level. Special Application 2: Lithium-ion Battery ElectrolyteLithium hexafluoroisopropoxide (LiPOT), as an electrolyte additive, can preferentially reduce the graphite anode to form a more stable SEI film, suppressing side reactions and improving cycle stability. After addition, the electrolyte contact angle with the Celgard separator decreases from 41.0° to approximately 26°, reducing interfacial impedance. The significance of Jiayuan 3N's purity lies in moisture control: the electrolyte is extremely sensitive to moisture; even trace amounts of water accelerate LiPF₆ hydrolysis, leading to capacity decay. Jiayuan 3N HFIP typically maintains moisture levels below several hundred ppm, while industrial-grade moisture fluctuations can directly degrade batch consistency of batteries. FAQQ1: Is Jiayuan 3N HFIP equivalent to electronic grade?A: No, they are not the same. 3N (≥99.9%) is the minimum threshold for electronic grade, while the industry forefront has reached 99.99% (4N) to meet the requirements of processes below 3nm. Purity and metal impurity indicators should be confirmed according to the specific process node. Q2: Why does the lithium battery industry focus on HFIP derivatives rather than HFIP itself?A: HFIP functions as a film-forming additive in the form of lithium hexafluoroisopropoxide, and is a raw material for synthesizing this type of additive. Jiayuan's 3N grade reduces the introduction of impurities, ensuring additive consistency and electrochemical performance. Q3: What are the core advantages of 3N HFIP compared to IPA in semiconductor cleaning?A: Low boiling point of approximately 24°C, resulting in faster drying and lower energy consumption; non-flammable, eliminating the risk of combustion and explosion; good water compatibility, allowing for rapid replacement of moisture on the wafer surface; 3N purity ensures no metal contamination is introduced.

99% Ammonium Bifluoride : Dual Advantages in Purity and Impurity Control

In the ammonium bifluoride market, purity is the most direct criterion for customers when selecting products. Our company offers high-grade ammonium bifluoride with a purity of ≥99%, and industrial-grade products with a purity of ≥98%, covering different application needs. The 99% purity specification is the focus of this article. What does 99% mean? Numerically, it's only one percentage point higher than 98%. However, in actual production processes, this one percentage point increase is accompanied by a comprehensive reduction in the impurity system.  First, let's look at the control of anions and moisture. Our company's 99% specification products have a drying loss of ≤0.5%, ensuring that the products are not prone to moisture absorption and clumping during storage and transportation, and that the feed flowability is stable; the ignition residue is ≤0.05%, keeping the total amount of inorganic impurities at an extremely low level; chloride is ≤0.005% and sulfate is ≤0.005%, with both indicators tightened simultaneously, effectively reducing the risk of side reactions in downstream reactions and reducing the hidden dangers of equipment corrosion. Metal ion control is the core advantage of the 99% specification. Iron content ≤0.005% means that for glass etching customers, the etched surface is less prone to yellowing, ensuring better light transmittance and appearance quality; for metal surface treatment customers, it means that coating adhesion is not affected by residual iron ions. Heavy metals ≤0.003% leaves room for application in fields highly sensitive to heavy metals, such as electronic chemicals and pharmaceutical intermediates. Another key indicator deserves separate mention: fluorosilicate ≤ 0.2%. Fluorosilicate is one of the most difficult impurities to separate during ammonium bifluoride production, and its content directly affects etching uniformity. In glass frosting processes, high fluorosilicate levels can lead to uneven surface haze; in metal processing, it may interfere with reaction consistency. Our company has consistently controlled this indicator below 0.2%, reflecting the maturity of our refining and purification processes. The industrial-grade 98% purity specification also features a white crystalline appearance and is suitable for common applications such as glass etching, metal surface treatment, and oil extraction acidizing, meeting the needs of industrial customers who require batch stability. 98% is the standard configuration for industrial-grade products, while the 99% purity specification implements stricter limits for impurity control, forming a clear selection gradient. Purity figures are merely the entry point; the impurity ledger is the real substance. The value of our 99% ammonium bifluoride lies in a complete set of quantifiable and verifiable limits for drying loss, ignition residue, chlorides, sulfates, fluorosilicates, iron, and heavy metals, allowing customers to make precise choices based on the actual needs of their processes. FAQQ1: What is the main difference between 99% ammonium bifluoride and 98% industrial grade products?A: The 99% specification adheres to stricter limits for impurity control, including drying loss ≤0.5%, chloride ≤0.005%, sulfate ≤0.005%, fluorosilicate ≤0.2%, iron ≤0.005%, and heavy metals ≤0.003%. The 98% industrial grade is suitable for general industrial applications, while the 99% specification is geared towards applications with higher sensitivity to impurities, forming a clear selection gradient. Q2: What is the practical significance for customers if the fluorosilicate content of 99% specification is controlled below 0.2%?A: Fluorosilicates are among the most difficult impurities to separate during production, and their content directly affects etching uniformity. In glass frosting processes, excessively high levels can lead to uneven surface haze; in metal processing, they may interfere with reaction consistency. Maintaining fluorosilicate levels stably below 0.2% effectively ensures the stability of downstream customer processes across batches. Q3: What do iron and heavy metal indicators mean for glass etching and metal surface treatment customers?A: Iron content ≤0.005% prevents yellow spots on the etched glass surface, ensuring light transmittance and appearance quality; heavy metals ≤0.003% ensures that the adhesion of coatings during metal surface treatment is not affected. These two indicators are crucial for 99% of the specifications to be compatible with high-end industrial scenarios. Q4: How can customers determine whether to choose the 99% or 98% specification?A: The key factor is the process's tolerance for impurities. For routine glass etching, oil extraction acidizing, and ceramic manufacturing, 98% industrial grade is sufficient. If there are specific requirements for etching uniformity, color consistency, or heavy metal residue, we recommend choosing the 99% specification. Customers can request complete testing data for both product grades to make an accurate selection based on their actual process parameters.

[Rare Gases Monthly Review]: Helium market continues its downward trend, krypton prices weaken (September 2026)

Market AnalysisIn September 2026, the domestic rare gas market showed a mixed performance. Helium prices continued to decline overall, krypton prices shifted downwards, while xenon and neon prices remained stable but trading was weak. Market supply was relatively abundant, downstream procurement was cautious, and the overall trading atmosphere was moderate.  Regarding helium, the average monthly price of bottled high-purity helium continued to decline. Market supply remained ample, but downstream purchasing activity was weak, with companies primarily focusing on price reductions to move inventory, leading to a continued downward trend in bottled helium prices. Bulk intermediaries shifted their purchasing focus downwards, with companies in East China lowering prices to move inventory, and some low-priced transactions continuing to decline; mainstream transactions in Southwest China followed suit. The market prices for both imported and domestically produced high-purity helium in tubular form also continued to decline. Imported supplies remained plentiful, and domestic helium production continued to increase, resulting in an overall sufficient supply. In this downward trend, channel purchasing activity was generally low, and with the upcoming holidays, downstream procurement slowed, causing market prices to drop rapidly. In Inner Mongolia and Shaanxi, mainstream ex-factory prices for high-purity helium in tubular form continued to decline, market trading was subdued, and downstream buyers were largely unwilling to accept goods, adopting a wait-and-see attitude. Regarding xenon, the average market price remained stable, but the transaction focus shifted downwards. The supply-demand imbalance has not yet eased, and prices continued to decline, with some low-priced transactions occurring. Regarding krypton gas, while the nominal average market price remained stable, the actual transaction focus shifted downwards, with the monthly average price declining month-on-month. Downstream end-users purchased only as needed, anchored to actual production demands, and were cautious about stockpiling. Given the weak market conditions, factories and traders generally lowered their prices to compete for orders, accelerating inventory turnover and releasing supply. Regarding neon, market prices remained stable, transaction volume shifted downwards, channel inventory was ample, and the trading atmosphere was weak. Market OutlookLooking ahead, the high-purity helium market is expected to continue its downward trend in October 2026, with further room for price declines, but a sustained deep drop is unlikely. On the supply side, overall supply remains high: maintenance shutdowns at some Russian gas sources may reduce imports, but gas from the US and Germany continues to flow into the domestic market; coupled with the continued release of domestic helium production capacity, the increase in domestically produced tubular helium is significant, resulting in ample market supply. On the demand side, essential consumption from the medical and semiconductor industries provides basic support, but downstream end-users are driven by actual production schedules and are cautious in their purchasing, making large-scale restocking unlikely in the short term. It is expected that the average purchase price for imported tubular high-purity helium by intermediaries will continue to decline, with a larger drop in domestically produced tubular high-purity helium, and a corresponding reduction in bulk purchase prices for bottled high-purity helium.Xenon prices are expected to see a slight downward adjustment. Downstream demand remains weak, with only sporadic transactions for immediate needs. The market lacks positive support, and prices are likely to continue their downward trend in October. Domestic krypton prices are likely to continue their significant decline in October. Currently, downstream purchasing enthusiasm is low, and factories and traders face significant pressure to reduce inventory. Market players are generally lowering prices to compete for orders and accelerate inventory release and cash flow recovery. The neon market is expected to remain stable. In the short term, the spot market is quiet, with supply and demand approaching equilibrium. Producers and traders are mostly shipping close to cost, and there is no immediate incentive for significant price adjustments. Professional supplier, trustworthyIn the current volatile and adjusting rare gas market, choosing a stable and reliable supply channel is particularly important. Jiayuan has long focused on the rare gas business, possessing abundant resources and a professional service team in the fields of helium, xenon, krypton, and neon.
