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.2026-10-16
