. Formula: AlF3      
2. CAS No: 7784-18-1
3. M.W:83.98
4. Properties: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.
