Molecular formula: AIF3
Molecular Weight: 83.98 implementation standard: GB4292-2007
Physical and chemical properties:
Aluminum fluoride is white powder, needle-like crystallization, the specific gravity of 2.882-3.13g/cm3, sublimation temperature 1272℃, soluble in water, in hydrofluoric acid solution has a greater solubility: anhydrous fluorine
The chemical properties：aluminum are very stable, but at the high temperature of 300-400 ℃, aluminum fluoride containing certain crystalline water will hydrolyze to Al203 and release the addition of HF gas.
Mainly used for molten salt refining aluminum as electrolyte adjustment agent, but also for ceramic glaze, catalyst and non-metallic flux.
