Natural alunite fragmented, calcination, dehydration, leaching, settlement, obtained crystallization. Sulfuric acid can also be used for generating decomposition bauxite aluminum sulfate powder and potassium sulfate solution reaction, filtration, crystallization, centrifugal dewatering, drying in the system. Paper Industry for Rosin settlement agent, help purify the Choshui Shen agent, Photographic Paper hardener, foam rubber foam, help, help -- galvanized the conductive agent, and dyeing of Mordant, anti-Discharge Process-dye. Convergence can be used in cosmetics. Convergence on medicine for medicine, the symptoms and hemostatic medicine. Food agent for osteoporosis.

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 Contributing Factors. 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
