White or yellowish bean petal shaped particles, rods and blocks. The melting point is about 360 ℃, d 2.044. 380 ℃ is anhydrous. It is easy to absorb moisture and deliquescence in the air, absorbing carbon dioxide to produce potassium carbonate. Dissolve in 0.9 parts of water, 0.6 parts of boiling water, 3 parts of ethanol, 2.5 parts of glycerin, and release a lot of heat at the same time. Insoluble in ether. 0. pH value of Imol/L aqueous solution is 13.5. It is incombustible and highly corrosive. A large amount of heat is released when encountering water and steam to form corrosive solution. Neutralization reaction with acid and heat release.
