Potassium Fluoride

Potassium fluoride is colorless cubic crystal. It is soluble in water, soluble in hydrofluoric acid and liquid ammonia, slightly soluble in alcohol and acetone. The aqueous solution is alkaline and can corrode glass and porcelain. When heated to sublimation temperature, a little decomposition, but the activity of fused potassium fluoride is larger, can corrode refractory substances.
