Colorless cubic crystals, the appearance is often octahedral, or with the cube, rhombic dodecahedron to form a polymorphic shape, sometimes attached to the container wall and resembling a hexagonal plate, belonging to the type alum double salt, with glass luster.
Density, melting point. 9 molecules of crystal water are lost, and 12 molecules of crystal water are lost at 200, which are soluble in water and insoluble in ethanol. Alum has a sour taste, is cold, and poisonous.
Therefore, it has antibacterial effect, astringent effect, etc., and can be used as traditional Chinese medicine. Alum can also be used to prepare aluminum salts, baking powders, paints, tanning materials, clarifying agents, mordants, papermaking, waterproofing agents, etc.
