  • Fluosilisic acid (HrSiFu) is mainly produced as a by-product from the wet
    process of Phosphoric Acid production from fluorapatite
  • Fluosilicic acid is the feedstock for virtually all organic and inorganic fluorine-bearing hemicals.
  • The majority of the fluosilicic acid is converted to aluminium fluoride and cryolite
  • Fluosilicic acid is also commonly used for water fluoridation in several countries including the United States England, and Ireland.
  • In the U.S., about 40,000 tons of fluosilicic acid is recovered from phosphoric acid plants, and then used primarily in Water fluoridation, sometimes after being processed into sodium silicofluoride
  • The main characteristics of fluosilicic acid are its bactericidal and fungicidal effects, because of which there is some direct use as a sterilizing and impregnating agent in breweries and for wood protection
  • Fluosilisic acid will be marketed as input for water treatment plants as a fluoride source.
