Ammonium Bifluoride

Ammonium Bifluoride

Other names: ammonium bifluoride, ammonium hydrogen fluoride, ammonium acid fluoride, ammonium hydrofluoride, matter salt.

Ammonium hydrogenfluoride is a compound formed from ammonium fluoride and hydrogenfluoride, with hydrogen fluoride molecules occupying spaces in thecammonium fluoride crystal lattice. It is the major constituent inglass-etching fluid (though sometimes replaced by potassium hydrogenfluoride), etching occurring due to the fluorination of silicon:SiO2 (s) 4[NH4][HF2] (aq) → SiF4 (l) 4[NH4]F (aq) 2H2O (l)The structure of [NH4][HF2]contains tetrahedral [NH4] cations and linear [HF2] anions. Eachcation is surrounded by four fluorine atroms in a tetrahedron, withhydrogen - fluorine hydrogen bonds present between the hydrogen atomsof the ammonium ion and the fluorine atoms.

Main Use

Ammonium Bifluoride is used as glass etchant, antiseptic, disinfector, analytical reagent, the solvent in beryllia producing beryllium metal and the treatment of the surface of silicon steel plate. It is also used as the oxidant in producing pottery and aluminum magnesium alloy, the cleaning agent of boiler water-supply system an evap-orator system, the acidification treatment of sand in oil field, the fluorination reagent in organic synthesis and the extraction of rare element.
