Descripción general

Powder with a mesh size above 300, toxic. Hygroscopic. Highly soluble in water but insoluble in alcohol, soluble in hydrofluoric acid and liquid ammonia, slightly soluble in alcohol and acetone. Its aqueous solution exhibits alkaline reactions and can corrode glass and ceramics. It only slightly decomposes when heated to the sublimation temperature, but molten potassium fluoride is highly reactive and can corrode refractory materials. It can form adducts with hydrogen peroxide, such as KF·H₂O₂. Potassium fluoride has two hydrates: KF·2H₂O and KF·4H₂O. When crystallized from aqueous solutions below 40.2°C, the dihydrate (KF·2H₂O) is obtained, which forms monoclinic crystals. The dihydrate can dissolve into crystalline water at 41°C. Used as a complexing agent, for spot analysis of tantalum, a fermentation inhibitor, and a food preservative.
