Potassium fluoride is used to frost and etch glass, as in the manufacture of some optical glasses, and to make insecticides, pesticides, and disinfectants. Potassium fluoride is irritating to the skin, eyes, and respiratory system.

Potassium fluoride, represented by the chemical formula KF, is an inorganic compound comprising an alkali metal potassium and monoatomic anion fluoride. It exists in its solid state or aqueous solution form, with the mineral carobbiite being the naturally occurring KF.

The compound potassium fluoride (KF) results, and since the potassium and fluoride ions have equal but opposite charges, the compound is neutral (but not the individual ions in the compound)

Used in insecticides, solder flux and etching glass. Potassium fluoride is a fluoride salt having K+ as the counterion. It has a role as a poison. It is a fluoride salt and a potassium salt.
