What is Fluosilicic Acid used for?
Fluosilicic acid (H2SiF6) is an inorganic compound that consists of potassium cations and the hexafluorosiliate IV dianion. It is mainly used to produce sodium fluoride as a defluorinating agent for glasses and ceramics. This application accounts for about 80% of the world’s consumption. Fluosilicic acid is also used to fluoridate water supplies in a process called water fluoridation. This also serves as a compound for the etching of metal and preservation of wood, in addition to being used as a catalyst with specific chemical processes.
