Ammonium hydrogen fluoride is a compound formed from ammonium fluoride and hydrogen fluoride, with hydrogen fluoride molecules occupying spaces in the ammonium fluoride crystal lattice. It is the major constituent in glass-etching fluid (though sometimes replaced by potassium hydrogen fluoride), etching occurring due to the fluorination of silicon:
SiO2 (s)+ 4[NH4][HF2] (AG) SiF4 (l) + 4[NH4]F (AG) + 2H2O (l)
Our huge range of chemical compound is extensively used in anodizing of aluminum, wood preservative and glass cleaning, etching & pickling. Available at competitive prices, our offered Ammonium Bifluoride is well appreciated in the market for its salient properties such as purity, longer shelf life and accurate composition.

Potassium Bifluoride
Name: Potassium bifluoride
Synonyms: Potassium hydrogen fluoride
CAS No.: 7789-29-9
Molecular Formula: KHF2
Molecular weight??? 78.10
Character
It is a colourless tetragonal or cubic crystal with slightly acidic smell and relative density of 2.37, mp 225°C. It is easy soluble in water, insoluble in alcohol. Its aqueous solution is acidity. It is stable in dry air, but decomposes to release hydrogen fluoride in humid air. It gives of HF when heated to 310°C, and the steam pressure of hydrogen fluoride could reach 0.10325Mpa(l atm) at 400°C. The activity of fused potassium bifluoride is greater than potassium fluoride. It is toxic and caustic.
Specification: 99%min
Package: 25kg/bag
Applications:Potassium Bifluoride is used for manufacturing wood preservatives.It is used in the production of soldering agents and brazing. It is also used as a catalyst for polymerization. It is used as a component of electrolyte and fluorine production. It is used in glass industry for etching and manufacturing special optical glasses. Flux for Silver Solders and constituent of Brazing Flux formulation. Catalyst in the Alkylation of benzene with olefins.
