Potassium fluoride/POTASSIUM FLUORIDE（FK）

CAS:7789-23-3

nature:

Colorless cubic crystal or white powder, soluble in water, alkaline, insoluble in ethanol, easy to absorb moisture and irritating. It is easy to form KF • 2H2O at 42 ° C Water solubility 92g/100ml C=18 ° C.

Melting point 858 ° C, boiling point 1502 ° C, density 2.48g/cm

Purpose:

1. Synthesis of pharmaceuticals, pesticides, dye intermediates and fine chemicals

2. Used as metal smelting and welding assistant

3. The electroplating process includes pre-treatment and electroplating. In the pre-treatment process of materials, potassium fluoride is mainly used for neutral etching treatment.

4. In the glass carving industry, potassium fluoride is used together with ammonium fluoride, ammonium bifluoride, sulfuric acid, etc. to carve glass. Its working principle is the same as that of ammonium fluoride and ammonium bifluoride, but it is softer than that of ammonium fluoride.
