magnesium fluosilicate

magnesium fluosilicate Molecular formula: MgSiF6 ^. 6H2O

magnesium fluosilicate Molecualr weight: 274.48

magnesium fluosilicate Physical and chemical feature: It is white rhombus crystal or acicular crystal. It is difficult for deliquescence but can be efflorescent to lose the water in crystal. When temperature is over 80, it will dewater and dissolve with gas of silicon fluoride. It dissolves at the melting point, easy to disslove in water and diluted acid, difficult to dissolve in HF. It doesn't dissolve in alcohol. Its aqueous solution takes acidic property. If reacted on alkali, it can take the form of relevant fluoride and silicon dioxide.
