Applications
1. Additive for aluminum metal production. Aluminium fluoride (AlF3) is widely used for the production

of aluminium by electrolysis asan additive . Used in combinationwith cryolite, AlF3lowers the melting

point to below 1000 °C to form a molten salt that dissolves the aluminum oxide. This melt solution is

then electrolyzed to produce aluminummetal.

2. Optical materials and photonics applications.

AlumDental Apparatus inium fluoride is used in combination with zirconium fluoride as an ingredient for the production of fluoroaluminate glasses. Like magnesium fluoride, aluminium fluoride isalso used as a low-index optical thin film, particularly when far UV transparency is required. Package & Printing Service

Its deposition by physical vapor deposition (PVD), particularly by evaporation, is preferred using analuminum fluoride target.
