Application

Aluminum fluoride plays a crucial role in various industrial and scientific applications. Primarily, it is an essential additive in the production of aluminum, where it helps to lower the melting point of cryolite, thereby enhancing the conductivity of the electrolyte. This process significantly reduces the energy required for aluminum production by allowing electrolysis to occur at lower temperatures. Beyond its application in aluminum production, aluminum fluoride serves as a flux in ceramic glazes and enamels, aiding in the manufacture of aluminum silicate and acting as a catalyst. Additionally, it can be employed as a barrier to inhibit the oxidation of aluminum mirrors and is used in the formation of fluoroaluminate glasses when combined with zirconium fluoride. In the scientific realm, aluminum fluoride complexes with proteins are instrumental in examining the mechanisms of phosphoryl transfer reactions, which are vital in biological processes such as metabolism, growth, and differentiation. Moreover, its application extends to agriculture, where it can inhibit fermentation, and in optics, where physical vapor deposition of aluminum fluoride provides a low-index optical thin film with far UV transparency.
