Characteristic
Sodium hexafluorosilicate occurs naturally as the rare mineral malladrite found within some volcanic fumaroles.Moisture sensitive. Incompatible with oxidizing agents and water.
Chemical formula:Na2[SiF6]
Molar mass:188 g/mol
Appearance:white granular powder
Odor:odorless
Density:2.7 g/cm3
Solubility in water:0.64 g/100 mL (20 °C);1.27 g/100 mL (50 °C);2.45 g/100 mL (100 °C)
Solubility:insoluble in alcohol
Refractive index (nD):1.312
Crystal structure:trigonal
Application
Sodium hexafluorosilicate is used as a additive for water fluoridation, opal glass raw material and in ore refining. It is also used in the preparation of other fluoride chemicals like sodium fluoride, sodium hexafluoroaluminate, potassium hexafluorosilicate, ammonium fluoride and calcium fluoride. It finds application as flotator, component for wet etching, wood preservative, brazing flux and welding compound. It is an active component of concrete.
