Application:
Aluminum fluoride is one of the most important additives in the industrial production of aluminum. The usage of aluminum fluoride can lower the melting point of cryolite and better the physical and chemical properties of the electrolyte. In the aluminum production, aluminum oxide is dissolved in a solution of cryolite. By passing an electrical current through the solution, aluminum is produced. Nevertheless, cryolite solution melts at about 1000°C. When aluminum fluoride is added, electrolysis can happen in the cryolite solution at a temperature 40-60°C lower, reducing the required amount of energy to produce aluminum.
Aluminum fluoride is used as a barrier layer to retard oxidation of aluminum mirrors.
It is used as a flux in ceramic glazes and enamels, in the manufacture of aluminum silicate, and as a catalyst.
Aluminum fluoride complexes with proteins can be used to study the mechanistic aspects of phosphoryl transfer reactions in biology, which are of fundamental importance as phosphoric acid anhydrides such as ATP and GTP control most of the reactions involved in metabolism, growth and differentiation.
Aluminum fluoride, together with zirconium fluoride, is used to produce fluoroaluminate glasses. In agriculture, aluminum fluoride can be used to inhibit fermentation. Physical vapor deposited aluminum fluoride can be used as a low index optical thin film in situations when far UV transparency is required.
