Hexafluorosilicic acid（Cat No.:M079227）, with the chemical formula H2SiF6, is a colorless, corrosive liquid widely used in water fluoridation, ceramics manufacturing, and the production of aluminum and other metals. This inorganic compound forms from the reaction of fluorine gases with silica-containing minerals during industrial processes. It is notable for being a source of fluoride ions, essential in public health for preventing dental caries when added to water supplies. However, due to its strong acidity and reactivity, handling hexafluorosilicic acid requires stringent safety measures to avoid harmful exposures and environmental impact.
