[¦flü·ə·sə′lis·ik ′as·əd]
(inorganic chemistry)
H2SiF6 A colorless acid, soluble in water, which attacks glass and stoneware; highly corrosive and toxic; used in water fluoridation and electroplating. Also known as hydrofluorosilicic acid; hydrofluosilicic acid.

Fluosilicic Acid


H2SiF6, a strong inorganic acid. It can exist only in an aqueous solution; in the free state it decomposes into silicon tetrafluoride, SiF4, and hydrogen fluoride, HF. Fluosilicic acid is a powerful disinfectant, but it is primarily used in the preparation of its salts (fluosilicates).

A third factor is that ammonia added to chlorine to produce chloramine will also react with fluosilicic acid to produce ammonium fluosilicate, an established solvent for copper alloys.
Related research showed that in communities where fluosilicic acid is added to the drinking water, the "prevalence of children with elevated blood lead (PbB > 10 micrograms/dL) is about double that in non-fluoridated communities.
Concentration of 30-54% phosphoric acid releases large volumes of silicon tetrafluoride and in most processes is recovered as fluosilicic acid.
