Aluminum fluoride products can be divided into anhydrous aluminum fluoride, dry process aluminum fluoride, and wet process aluminum fluoride. Anhydrous aluminum fluoride has a high main content and extremely low impurity content, which can effectively adjust the electrolyte molecular ratio, reduce hydrolysis losses in aluminum electrolysis production, improve the quality of aluminum ingots, and reduce production costs

Application:
It is a necessary raw material in the production of electrolytic aluminum. As an adjusting agent for the melting electrolyte of alumina, it can lower the electrolysis temperature, enhance conductivity, reduce molecular ratio, and facilitate the electrolysis of alumina; It is also used as a fermentation inhibitor in the production of alcohol. Used as a flux for the outer glaze and enamel glaze of ceramics, and as a flux for non-ferrous metals. Used for welding fluid in metal welding. Used for manufacturing optical lenses. It is also used as a catalyst for organic synthesis and as a raw material for synthesizing cryolite.
