Molecule Structure Image



Potassium fluoride is an alkali metal halide and occurs naturally as the rare mineral carobbiite. After hydrogen fluoride, potassium fluoride is the primary source of the fluoride ion for applications in manufacturing and in chemistry. The primary uses of potassium fluoride are in the metallurgical industry, including soldering fluxes and in tin plating. It is also widely used as a fluorinating agent in organic synthesis to replace other halide atoms with fluorine. This includes the manufacture of a number of pesticides and insecticides. It is also a useful catalyst in the manufacture of polyurethanes.
