Ammonium fluoride is widely used in various industrial applications due to its unique properties. It is commonly employed as a glass etchant in the manufacturing of glass and ceramics, where it helps create frosted or matte finishes on surfaces. In the electronics industry, it serves as a cleaning agent for silicon wafers, removing oxides and impurities to ensure high-quality semiconductor production. Additionally, it is utilized in wood preservation treatments to protect against fungal decay and insect damage. In analytical chemistry, it acts as a reagent for fluoride ion determination and in metal surface treatments to enhance corrosion resistance. Its role in organic synthesis includes acting as a fluorinating agent to introduce fluorine atoms into molecules.
