hydrofluorsilikat

Hydrofluorsilicate is a chemical compound with the general formula H2SiF6. It is a colorless, acidic solution that is often found in industrial applications. The term hydrofluorsilicic acid is commonly used to refer to aqueous solutions of this compound. It is derived from the reaction of hydrogen fluoride with silica. Hydrofluorsilicate is a strong acid and is corrosive. It is also known as silicofluoridic acid or fluorosilicic acid.

Industrially, hydrofluorsilicate is produced as a byproduct of phosphate fertilizer manufacturing. It is also used in various applications, including water fluoridation, where it is added to public water supplies to help prevent tooth decay. Other uses include metal surface treatment, glass etching, and as an ingredient in some concrete hardening agents. It can also be found in some insecticides and rodenticides, although its use in these applications is often regulated. Due to its acidic and corrosive nature, proper handling and safety precautions are necessary when working with hydrofluorsilicate.
