Colorless cubic crystals, glass appearance often has octahedral, or cube, rhombic dodecahedron form poly shape, the shape of the six-party plate-sometimes to the {111} planes attached to the wall of the vessel, belonging to the α-alum double salt, luster. Density 1.757g/cm3, 92.5 ° C melting point. 64.5 ℃ lost nine of molecular crystals lose 12 molecules of water, 200 ℃ crystal water, soluble in water, insoluble in ethanol. Alum sexual taste sour, cold, toxic. Therefore antibacterial effect, convergence effect, can be used as traditional Chinese medicine. Alum can also be used for the preparation of aluminum salt, baking powder, paint, tanning, clarifying agent, mordant, paper, waterproofing agents. Potassium alum is colorless and transparent, massive or crystalline powder, odorless, non-toxic, slightly sweet taste and astringent, Convergence, soluble in water, acidic aqueous solution, heat easily lose crystal water and become white powder. Its main use is reflected in the following aspects: agriculture: seed disinfection, animal medical treatment, solid root hair Miao, Zhuang rod pod and alkaline soil applied potassium fertilization. Light chemical aspects: water purification, paper sizing, coatings, printing and dyeing, lake pigments, pharmaceutical and paint making, tanning, fibreboard processing, Videos fixing Caine film, as well as for the rubber and metallurgy; colored glass industry. Food Industry: Food agent. Fermentation, vermicelli processing, aquatic marinated, food preservatives and food additives.
