Potassium bifluoride
Product Basic Parameter of Physical Chemistry:
Product name: Potassium bifluoride (KHF2)
Molecular weight: 78.10
English name: potassium bifluoride
Characters: 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.

Quality standard:
Combined acid Sulphate(SO4) Iron(Fe) Heavy metals(Pb)
25-26% =0.05% =0.005% =0.003%
Fluorosilicate(K2SiF6) Chloride(Cl) Moisture (H2O)
