• Uses: Ammonium hydrogen fluoride is used as a chemical reagent in analysis and an antiseptic. It is also used in ceramics, electroplating, component of glass etchants as well as food processing equipment disinfectant. It acts as an intermediate in the production of hydrofluoric acid from hexafluorosilicic acid. In manufacture of Mg and Mg alloys; in brightening of Al; for purifying and cleansing various parts of beer-dispensing apparatus, tubes, etc., sterilizing dairy and other food equipment; in glass and porcelain industries; as mordant for aluminum; as a "sour" in laundering cloth. In lab production of HF.
