Potassium fluoride/POTASSIUM FLUORIDE（KF/FK）
Product Details:
CAS number: 7789-23-3
Chemical formula: FK
Molecular weight: 58.1
Introduction:
Potassium fluoride is a kind of salt, also known as potassium fluoride salt, which is white monoclinic crystal or crystalline powder, salty in taste, easy to absorb moisture, soluble in water but not in ethanol. Its aqueous solution is alkaline and can corrode glass and porcelain. Therefore, Chemicalbook can be used as a variety of glass etching, welding flux, wood preservatives, agricultural insecticides, pesticide intermediates, pharmaceutical industry raw materials, and organic fluorinated raw materials. It plays an indispensable role in construction, chemical industry and agriculture.
