Aluminum fluoride Aluminum fluoride is colorless or white crystals. Insoluble in water, insoluble in acid and alkali. It is very stable in nature and can be hydrolyzed under heating. Mainly used for aluminum. Aluminum trichloride and hydrofluoric acid, ammonia water system. Chemical properties: There was no reaction with liquid ammonia or concentrated sulfuric acid, or with hydrated potassium hydroxide. Not reduced by hydrogen, strong heat does not decompose but sublimates, and its properties are very stable. Heating to 300-400°C can be partially decomposed by steam into hydrogen fluoride and aluminum oxide.
