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.[1] Preparation and properties of fluosilicic acid have been reported.[2] Fluosilicic acid can be obtained as a major byproduct of phosphate fertilizer industry.[3]It can be used in the preparation of sodium fluorosilicate, via neutralization with sodium chloride.[4] It can also undergo neutralization with ammonia to produce ammonium fluoride and silica.[3]
- Application: Fluosilicic acid (FSA, H2SiF6) has been used in the following studies:Fluoridation of fluoridated municipal water supplies.[5]Surface modification of calcium carbonate.[6]Liquid phase deposition (LPD) of silica.[7]
