Product features of potash alum
-- Also known as potassium alum (potash alum), Alumina, the Health alum, alum. Colorless cubic octahedral crystal cube or monoclinic crystal. . No foul, or slightly sweet convergence.
--1.757g/cm3 density. 92.5 ° C melting point. At 64.5 ° C lost nine crystal water, 200 ° Close all white crystalline water into cavernous Anhydrous become white powder burn alum. 92.5 ° C melting point. Dissolved in water (12.2%, 25 ° C), 1% aqueous solution of pH 4.2, in the water hydrolysis into aluminum hydroxide colloid was almost insoluble in alcohol. Extreme water-soluble and water-soluble and acid, dissolved in ethanol and acetone.
