Fluorosilicic acid solution is widely used in water fluoridation to improve dental health by reducing the incidence of cavities. It is added to public water supplies in controlled amounts to maintain optimal fluoride levels. Additionally, it serves as a key ingredient in the production of fluoride-based chemicals, such as sodium fluoride and aluminum fluoride, which are used in various industrial processes. In the manufacturing sector, it is utilized for metal surface treatment and as a cleaning agent to remove impurities. It also finds application in the ceramics and glass industries, where it acts as a flux to lower melting points and enhance material properties. Furthermore, it is employed in the production of herbicides and pesticides, contributing to agricultural practices.
