The company's products are widely used in cutting-edge fields such as precision manufacturing cleaning, electronic heat dissipation and cooling, new energy, and semiconductor testing, and the company is committed to providing global customers with high-performance, low-environmental-impact fluorochemical solutions.

Changzhou Jiayuan Chemical Co., Ltd. will continue to focus on the fluorochemical industry chain, promote the technological iteration and industrialization of green fluorosolvents, and contribute to the sustainable development of the industry.

In the pursuit of energy efficiency and productivity gains within the aluminum electrolysis industry, aluminum fluoride (AlF₃) serves as a key inorganic fluoride flux. Leveraging its stable physicochemical properties—insolubility in water and most acids or alkalis, and sublimation upon heating rather than decomposition—AlF₃ plays an irreplaceable role in high-temperature electrolyte systems. Its core function lies in effectively lowering the melting point of alumina while enhancing the electrical conductivity of the electrolyte, establishing it as an essential auxiliary material in modern aluminum metallurgy.

Taking the industrial-grade aluminum fluoride supplied by Changzhou Jiayuan Chemical Co., Ltd. as an example, the product adheres to strict technical specifications. Typical parameters show an actual measured purity of 99.95%, with extremely tight control over critical impurities: iron (Fe) content below 5 ppm (typical value 2.2 ppm), while metallic elements such as cobalt, chromium, titanium, copper, manganese, nickel, and vanadium are each kept below 1 ppm. This combination of high purity and low impurity levels makes it suitable for demanding industrial applications.

Downstream applications of aluminum fluoride are concentrated in the following areas:

Aluminum Electrolysis Industry: As a smelting flux, it is added to aluminum reduction cells to effectively lower the melting point of alumina and improve the conductivity of the electrolyte, thereby significantly enhancing production efficiency and energy savings.

Alcohol Fermentation: In alcohol production, aluminum fluoride acts as an inhibitor of secondary fermentation. It regulates microbial activity, suppresses undesirable side reactions, and improves the yield of the main product.

Ceramic and Enamel Industry: As a flux and a component of ceramic glazes, it reduces the melting temperature of the glaze and improves the surface gloss, leveling, and mechanical strength of the finished product.

Non-Ferrous Metal Smelting: It is used as a flux in the smelting of other non-ferrous metals (such as copper and magnesium), assisting in impurity removal or melt protection.

In summary, industrial-grade aluminum fluoride, by virtue of its distinct physicochemical properties, plays a critical role in the aluminum industry and various chemical and materials sectors. Changzhou Jiayuan Chemical supplies a product that, thanks to its compliant parameters and stable purity, is well-suited for the above-mentioned application scenarios with strict impurity requirements.
