Hydrofluosilicic Acid


Hydrofluosilicic Acid is the inorganic compound with the formula H2SiF6 and we ensure to supply it in the safest possible manner. It is supplied to the fertilizer industry. It has also been procured from us for treatment of potable water.

The acid accessible by us is encountered as an equilibrium mixture with hexaflurorosilicate anion (SiF62−). It is a by-product, which developed from the reaction of fluoroapatite with sulfuric acid that produces HF and than in turn reacts with silicate minerals SiO2 + 6 HF H2SiF6 + 2 H2O.

This solution of Hydrofluosilicic Acid reacts faster with t-butyldimethysilyl (TBDMS) ethers than triisopropylsilyl (TIPS) ethers. It is also used as wood conservation agents. Moreover, the compounds used are aluminum and magnesium hexafluorosilicate. Hydrofluosilicic Acid is widely used or water fluoridation in several countries such as United States, Australia, and Ireland.

H2SiF6 is commonly used for water fluoridation in several countries including the United States, Great Britain, and Ireland.

H2SiF6 is a reagent in organic synthesis for cleaving Si-O bonds of silyl ethers. It is more reactive for this purpose than HF. It reacts faster with t-butyldimethysilyl (TBDMS) ethers than triisopropylsilyl (TIPS) ethers.

Hexafluorosilicic acid and the salts are used as wood preservation agents. The aluminium and magnesium hexafluorosilicate are two used compounds.


Hexafluorosilicic acid releases hydrogen fluoride when evaporated, so it has similar risks. It is corrosive and may cause fluoride poisoning; inhalation of the vapors may cause lung edema. Like hydrogen fluoride, it attacks glass and stoneware.
