Application

Descriptions:

  • Sodium fluorosilicate is white crystalline powder.

  • Sodium fluorosilicate is odorless and tasteless.

  • Sodium fluorosilicate has moisture absorption capability.

  • Sodium fluorosilicate can be dissolved in a solvent such as ethyl ether but insoluble in alcohol.

  • Sodium fluorosilicate is slightly soluble in water. The solubility in acid is greater than that in water.

  • Sodium fluorosilicate can be decomposed in alkaline solution, generating sodium fluoride and silica.

  • Sodium fluorosilicate is corrosive and toxic.

Uses:

  • Sodium silicofluoride can be used in pharmaceutical industry.

  • Sodium silicofluoride can be used for fluoridation of drinking water.

  • Sodium silicofluoride can be used as fluxing agent in glass and vitreous enamel frits.

  • Sodium silicofluoride can be used as filling agent in plastic industry.

  • Sodium silicofluoride can be used as coagulating agent in natural rubber and latex products.

  • Sodium silicofluoride can be used as additive in metallurgy of aluminium and in clad layer of galvanized zinc, nickel and iron.

  • Sodium silicofluoride can be used to instead arsenious insecticides and rodenticides for pest control in agriculture.
