Short description

Amoni Bifluoride- Ammonium Bifluoride- NH4HF2 Origin: China Packing: 25kg / bag Purity:> 97% Application: Used to treat metal surfaces, create glass surface patterns, used as fungicides and wood preservatives Ammonium hydrogen fluoride is the inorganic compound with the formula NH4HF2 or NH4F·HF. It is produced from ammonia and hydrogen fluoride. This colourless salt is a glass-etchant and an intermediate in a once-contemplated route to hydrofluoric acid. Ammonium bifluoride is a component of some etchants. It attacks silica component of glass: SiO2 + 4 [NH4][HF2] → SiF4 + 4 NH4F + 2 H2O Potassium bifluoride is a related more commonly used etchant. Ammonium bifluoride has been considered as an intermediate in the production of hydrofluoric acid from hexafluorosilicic acid. Thus, hexafluorosilicic acid is hydrolyzed to give ammonium fluoride, which thermally decomposes to give the bifluoride: H2SiF6 + 6 NH3 + 2 H2O → SiO2 + 6 NH4F 2 NH4F → NH3 + [NH4]HF2 The resulting ammonium bifluoride is converted to the sodium bifluoride, which thermally decomposes to release HF.

Technical Data

Origin: China

Ammonium hydrogen fluoride is the inorganic compound with the formula NH4HF2 or NH4F·HF. It is produced from ammonia and hydrogen fluoride. This colourless salt is a glass-etchant and an intermediate in a once-contemplated route to hydrofluoric acid.

Ammonium bifluoride is a component of some etchants. It attacks silica component of glass:

SiO2 + 4 [NH4][HF2] → SiF4 + 4 NH4F + 2 H2O

Potassium bifluoride is a related more commonly used etchant.

Ammonium bifluoride has been considered as an intermediate in the production of hydrofluoric acid from hexafluorosilicic acid. Thus, hexafluorosilicic acid is hydrolyzed to give ammonium fluoride, which thermally decomposes to give the bifluoride:

H2SiF6 + 6 NH3 + 2 H2O → SiO2 + 6 NH4F
2 NH4F → NH3 + [NH4]HF2

The resulting ammonium bifluoride is converted to the sodium bifluoride, which thermally decomposes to release HF.
