 Sodium fluorosilicate 



  • It can be used in agricultural pesticides, enamel opalescent agents, opalescent glass corrosive agents, wood preservatives To be the raw material of other fluoride goods.

  • Used in the smelting of beryllium and aluminum

  • Used in medicine, leather, rubber industry, etc.

  • It can be used as a coagulant for water glass combined with refractories. Due to the relatively low solubility of sodium fluorosilicate in water, its reaction with water glass is slow and gradual, which is not only beneficial to the construction but also has a high density and strength of the hardened material.

  • Used as cid-resistant cement hygroscopic agent, drinking water fluorinating agent, etc.
