Properties: Clear or white, rhombohedra or acicular crystal, odorless. The relative density is 1.788.The melting point is 120°C(decomposition).It is hard to deliquesce. But the crystal water will be lost under efflorescence. It is decomposed by dehydration when the temperature is over 80°C, and at the same time gives out silicon tetrachloride gas. It dissolves easily in water, also in dilute acids, but hardly dissolves in hydrofluoric acid and insolubilizes in alcohols. Its water solution presents an acidic nature. When reacted on alkalis, it will generate relative fluor----complex and silica. Poisonous!
