Products Description of Sodium fluorosilicate CAS#16893-85-9

Sodium fluorosilicate seems as white crystal, crystalline powder or colorless hexagonal crystals. It is odorless and tasteless. Its relative density is 2.68; it has moisture absorption capability. It can be dissolved in a solvent such as ethyl ether however insoluble in alcohol. The solubility in acid is larger than that in water. It can be decomposed in alkaline solution, producing sodium fluoride and silica. After searing (300 ℃), it is decomposed into sodium fluoride and silicon tetrafluoride.

Product Application of Sodium fluorosilicate CAS#16893-85-9

Sodium hexafluorosilicate is used as a additive for water fluoridation, opal glass uncooked cloth and in ore refining. It is additionally used in the education of different fluoride chemical compounds like sodium fluoride, sodium hexafluoroaluminate, potassium hexafluorosilicate, ammonium fluoride and calcium fluoride. It finds utility as flotator, aspect for moist etching, wooden preservative, brazing flux and welding compound. It is an energetic factor of concrete.
