Potassium fluoride is the chemical compound with the formula KF. After hydrogen fluoride, KF is the primary source of the fluoride ion for applications in manufacturing and in chemistry.
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.
Potassium Fluoride is a white, crystalline (sand-like) powder with a sharp, salty taste. It is used in etching glass, as a preservative, and as an insecticide.
Potassium fluoride is prepared by dissolving potassium carbonate in hydrofluoric acid. Evaporation of the solution forms crystals of potassium bifluoride. The bifluoride on heating yields potassium fluoride: ... Potassium chloride converts to KF upon treatment with hydrogen fluoride.
