Ammonium fluoride is colorless needle-like or lobate crystal, which is ionic compounds. It tend to deliquesce in air. When heating, it breaks up to ammonia and hydrogen fluroide. NH4F dissolve in water and alcohol, but not in acetone and liquid ammonia. It corrode glass. Hydrofluoric acid anhydrous and liquid ammonia are the raw material.
NH4F is a widely used compound known for its effectiveness in ethcing, cleaning, and catalysis across various industries. Its ability to react with silica and other materials has made it a staple in sectors such as electronics, glass manufacturing, and metal processing. With its versatile properties, ammonium fluoride serves as a crucial component in the creation of high-precision surfaces, as well as in applications where controlled chemical reactions are essential.

Applications
NH4F solution can be as detergent and corrosive, which can confect with hydrofluoric acid to get buffer solution. Its MOS grades are mainly for integrated circuit of medium, large scale. The BVIII grades are mainly for IC production. It play a role in producing beryllium metal from beryllium oxide.
Its uses include extraction of rare elements, etching agent of ground glass, chemical polish of metal surface treatment, sanitizer and aseptic of making wine and mordant of fiber.
Ammonium fluoride get uses in ceramic and magnesium alloy. It can etch titanium wafer and silicon wafer. It is a kind of analytical reagent and covering agent too.
