Chemical properties: highly soluble in water, aluminum sulfate in pure sulfuric acid can not be dissolved (just coexist), in sulfuric acid solution and sulfuric acid jointly dissolved in water, so the solubility of aluminum sulfate in sulfuric acid is the solubility of aluminum sulfate in water. Crystallized water containing 18 molecules at room temperature is 18-water aluminum sulfate, and the industrial production is mostly 18-water aluminum sulfate. Containing anhydrous aluminum sulfate 51.3%, even if 100 ° C will not be self-soluble (dissolved in its own crystal water). It is not easy to lose crystal water through weathering, it is relatively stable, it will lose water when heated, and it will decompose into oxide of alumina and sulfur at high temperature. Heating to 770ºC begins to decompose into alumina, sulfur trioxide, sulfur dioxide and water vapor. Soluble in water, acid and base, insoluble in ethanol. The aqueous solution is acidic. After hydrolysis, aluminum hydroxide is formed. The aqueous solution can be boiled for a long time to produce basic aluminum sulfate. The industrial products are grayish-white flake, granular or block, with a light green color due to low iron salts, and yellow surface due to oxidation of low iron salts. The coarse product is a gray-white porous fine crystalline structure. Non-toxic, dust can irritate eyes.
Function and use: as a precipitating agent for rosin gum, wax emulsion and other rubber materials in paper industry, as a flocculant in water treatment, but also as a retention agent for foam fire extinguisher, raw materials for manufacturing industrial aluminum sulfate alum, aluminum white, oil decolorization, deodorization agent, raw materials for some drugs, etc. It can also manufacture artificial gemstones and high-grade ammonium alum. Products with arsenic content not greater than 5mg/kg can be used as flocculants for water treatment
