Aluminum sulfate (chemical formula Al2(SO4)3, formula weight 342.15), white orthorhombic crystalline powder, density 1.69g/mL (25ºC). In the paper industry, it is used as a precipitant for rosin gum, wax emulsion and other rubber materials, as a flocculant in water treatment, and as an internal retention agent for foam fire extinguishers, as raw materials for the production of alum and aluminum white, petroleum decolorization, deodorant, and some Raw materials for medicines, etc. It can also produce artificial gems and advanced ammonium alum. Aluminum sulfate, which accounts for about 50% of the total output, is used as a flocculant in the treatment of drinking water, industrial water and industrial wastewater, and accounts for about 40% of the total output of aluminum sulfate. When aluminum sulfate is added to this type of water, it can produce colloidal aluminum hydroxide flakes that can adsorb and precipitate bacteria, colloids and other suspended solids, which can be used in drinking water treatment to control the color and taste of the water.

1) Water/ Effluent Treatment
For purification of drinking water and waste water treatment, settling of impurities by means of precipitation and flocculation. 
2) Paper Industry
It helps in sizing of paper at neutral and alkaline pH, thus improving sizing efficiency and paper quality (reducing spots and holes, improving sheet formation and strength).
3) Textile Industry
For color fixing in Naphthol based dyes for cotton fabric. Paper-making sizing, sugar refining, casting, medicine refining, cement quick setting and cosmetics raw materials etc.

Aluminum sulfate is an inorganic compound with the formula Al2(SO4)3 and a molecular weight of 342.15. It is a white crystalline powder.

Melting point: 770℃
Density: 2.71g/cm3
Appearance: white crystalline powder.
Solubility: soluble in water, insoluble in ethanol.

1. Used as paper sizing agent in the paper industry to enhance the water resistance and impermeability of paper.
2. soluble in water can make the fine particles in water and natural colloids condensed into large flocculent, so removed from the water, so used as water supply and wastewater coagulant.
3. used as turbidity water purification agent, also used as precipitating agent, fixing agent, filler and so on. It is used as raw material (astringent) in cosmetics to suppress perspiration.
4. in the fire industry, with baking soda, foaming agent to form foam extinguishing agent.
5. analytical reagents, mordant, tanning agent, oil decolorizing agent, wood preservatives.
6. albumin pasteurization stabilizer (including liquid or frozen whole eggs, white or yolk).
7. can be used as raw materials for the manufacture of artificial gems and high-grade ammonium alum, other aluminates.
8. in the fuel industry, in the production of chromium yellow and color lake dye as precipitating agent, but also plays the role of solid color and filler.
9. used as an effective crosslinking agent for animal glue, and can improve the viscosity of animal glue. It is also used as the curing agent of urea-formaldehyde adhesive, and the curing speed of 20% aqueous solution is faster.

Alingite, a widely distributed rock-forming sulfate mineral, is called sodium alingite or sodium alingite when Na content exceeds K, and sometimes a small amount of Fe3+ replaces Al3+. Produced as sacs or thin layers within volcanic rocks such as rhyolite, trachyte and andesite, it is thought to be formed by chemical reactions between these rocks and escaped sulfur-containing vapors. Alingite is the alteration product of medium acid volcanic extruded rock produced by low temperature hydrothermal action.
