Product Description

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.Formula: AlF3CAS No.: 7784-18-1M.W.: 83.98EINECS : 232-051-1Appearance :White crystal or powderProperties: The product is a white needle crystal powder. SP.GR.2.882-3.13g/cm3,sublimation temp.1272.It's slightly soluble in water and greatly soluble in HF Liquid.The chemical property for the high density aluminium fluoride is very steady, but that contains certain crystal water will be decomposed into Al2O3 at high temprature with HF being released.

Application

In industry, fluorite is the main source of fluorine. It can extract and prepare fluorine and various compounds. It is also used as a cosolvent in steel-making to remove impurities, glass and enamel. In addition, there is a large demand for fluorite in the optical field.Acid grade fluorspar accounts for approximately 60-65% of total fluorspar production with the principal applications being:1. Aluminium production - used to produce aluminium fluoride (ALF3) which acts as a flux to lower the bath temperature in the manufacture of aluminium.2. Manufacture of hydrofluoric acid (HF) - the primary source of all fluorochemicals (the single largest consumer of fluorspar).

FAQ
