Sodium Silicofluoride is an odorless compound that appears as a white granular powder. It is manufactured through the neutralization of fluorosilicic acid with either sodium sulfate or sodium chloride. It is soluble in water up to 1.45 g/100 mL at 100 °C but it is insoluble in alcohol.
Density is at 2.7 g/cubic cm. It has a hexagonal crystalline structure. This compound also goes by other names including sodium fluosilicate, sodium fluorosilicate, sodium hexafluoridosilicate, and disodium hexafluorosilicate. It is typically packaged in 25 kg bags but larger quantities are readily available.
In many regions, it is added to public water for fluoridation as a means of minimizing tooth decay. It is also commonly used as opal glass raw material. Ore refineries use it in the process of producing metal. Other companies require the substance in the production of fluoride-based chemicals such as aluminum fluoride, cryolite, magnesium silicofluoride, and many more.
