Description
General description
High-silic fluoro silicic acids have been prepared. They have desired amount of extra silica upto 18% more than the composition as represented by H₂SiF₆. Preparation and properties of fluosilicic acid have been reported. Fluosilicic acid can be obtained as a major byproduct of phosphate fertilizer industry.It can be used in the preparation of sodium fluorosilicate, via neutralization with sodium chloride. It can also undergo neutralization with ammonia to produce ammonium fluoride and silica.
Application
Fluosilicic acid (FSA, H₂SiF₆) has been used in the following studies:
Fluoridation of fluoridated municipal water supplies.
Surface modification of calcium carbonate.
Liquid phase deposition (LPD) of silica.
