Sodium fluorosilicate (sodium hexafluorosilicate)

Sodium fluorosilicon (sodium hexafluorosilicate) 25kg, wholesale is a white, finely crystalline hygroscopic powder, sometimes with a yellowish or gray tint. It is an inorganic sodium salt of hydrofluorosilicic acid.

Poor solubility in water. Sodium silicofluoride is a toxic substance, like most fluoride salts. When interacting with concentrated acids, hydrofluoric acid is released. At high humidity, caking of the substance occurs, lumps are formed.

The chemical formula is Na2SiF6.

Where is it applied?
