MgSiF6.6H2O 98% Min, MgSO4.7H2O 0.5% Max,
H2SiF60.5%Max, H2O 0.5% Max
Insolublle Water 0.2% Max
Its water solution presents an acidic nature.When reacted on alkalis,it will generate relative fluor-complex and silica
Purity: 98.5%
Appearance: acicular crystal.Odourless.The relative density is 1.788.The melting point is 120°C(decomposition).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 easy 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
