AlF3 Sodium Aluminum Fluoride Lump / Powder With 99 High Purity

Aluminium fluoride (AlF3) as the flux of the non-iron metals

Aluminum fluoride is an inorganic substance with the chemical formula AlF₃, prepared by the reaction of aluminum hydroxide or metallic aluminum and hydrogen fluoride, or by the action of aluminum trichloride with hydrofluoric acid and ammonia.

Colorless or white crystal. Insoluble in water, insoluble in acids and bases. Stable in nature, can be hydrolyzed under the condition of heating.

Used in aluminum electrolysis as electrolyte regulator and catalyst.

Applications
1. Additive for aluminum metal production. Aluminium fluoride (AlF3) is widely used for the production of aluminium by electrolysis as an additive . Used in combination with cryolite, AlF3 lowers 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 aluminum metal.

2. Optical materials and photonics applications.

Aluminium fluoride is used in combination with zirconium fluoride as an ingredient for the production of fluoroaluminate glasses. Like magnesium fluoride, aluminium fluoride is also used as a low-index optical thin film, particularly when far UV transparency is required.

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