1. Used as paper sizing agent in the paper industry to enhance the water resistance and impermeability of paper;
2. Soluble in water, the fine particles and natural colloidal particles in water can condense into large floccule, which can be removed from the water, so it is used as a coagulant for water supply and wastewater;
3. Used as turbidity water purifier, also used as precipitation agent, fixing agent, filling agent, etc. Used in cosmetics as sweat inhibition cosmetics raw materials (astringent);
4. In fire industry, it is composed of foam fire extinguishing agent with baking soda and foaming agent;
5. Analytical reagent, mordant, tanning agent, oil decolorizing agent, wood preservative;
6. Albumin pasteurization stabilizer (including liquid or frozen whole egg, white or yolk);
7. Can be used as raw materials for the manufacture of artificial gems and high-grade ammonium alum, other aluminates;
8. Fuel industry, in the production of chrome yellow and color lake dye as a precipitant, but also play a role in fixing and filling agent;
9, curing agent (grease, water and other miscellaneous), albumin pasteurization stabilizer (including liquid or frozen whole egg, white or egg yolk). Maximum allowable use (FAO/WHO, 1984)0.036%. Used for papermaking, water purification, and used as mordant, tanning agent, medicine astringent, wood preservative, foam extinguishing agent and other artificial gem and senior ammonium alum production.
