Potassium Fluoride (KF) is a white monoclinic crystal or crystalline powder with a salty taste and easy to absorb moisture. Its relative density is 2.454, melting point is 858°C, and molecular weight is 58.09. Potassium Fluoride is soluble in water but insoluble in ethanol. Its aqueous solution is alkaline and can corrode glass and porcelain.

Potassium Fluoride is used in metal finishing, batteries, coatings, and photographic chemicals. It is utilized for the study of ion-specific swelling and de-swelling of ampholytic polymer gels as well as in the measurement of electronic polarizabilities of ions in polymers of alkali halides. It finds application in the electronic industry as a metal surface treatment product. It is used as a preservative, a food additive, a catalyzer, and a water-absorbing agent. In the Finkelstein reaction, it is actively involved in the conversion of chlorocarbons to fluorocarbons using polar solvents like dimethylformamide and ethylene glycol.
