Aluminum sulfate white orthorhombic crystal powder, density 1.69g/mL (25℃). In the paper industry, it is used as a precipitation agent for rosin gum, wax emulsion and other rubber materials, as a flocculant in water treatment, as a retention agent for foam fire extinguishers, as a raw material for the manufacture of alum and aluminum white, as a decolorizing agent for petroleum, deodorant, some Raw materials for medicines, etc. It can also manufacture artificial gemstones and ammonium alum.

About 50% of the total output of aluminum sulfate is used for papermaking, followed by flocculants in drinking water, industrial water and industrial wastewater treatment, accounting for about 40% of the total output of aluminum sulfate. When aluminum sulfate is added to this type of water, colloidal aluminum hydroxide flakes that can adsorb and precipitate bacteria, colloids and other suspended matter can be formed, which can be used in drinking water treatment to control the color and taste of water.

Physical properties:

Appearance and properties: white crystal, sweet; Solubility: soluble in water, insoluble in ethanol, etc.
The industrial products are gray-white flakes, granules or blocks, with a light green color due to the low iron salt content, and the surface turns yellow due to the oxidation of the low iron salt. The crude product is an off-white fine-grained porous material.
It is easily soluble in water. Aluminum sulfate is insoluble in pure sulfuric acid (only coexists), and is dissolved in water together with sulfuric acid in sulfuric acid solution. Therefore, the solubility of aluminum sulfate in sulfuric acid is the solubility of aluminum sulfate in water.
