Aluminum sulfate, also known as aluminum sulphate, is a versatile inorganic compound with the chemical formula Al2(SO4)3. Its main ingredients are sulfate and aluminum, supplemented with small amounts of calcium and potassium. This product is a white crystal that is easily soluble in water but insoluble in alcohol. The aqueous solution is acidic. The dehydration temperature is 86.5°C. It will lose crystal water when heated to 250°C. When anhydrous aluminum sulfate is heated to 300°C, it begins to decompose. The anhydrous substance has white crystals with pearl luster.
Solid aluminum sulfate (non ferrous) mainly comes in three forms: powder, granules, and flakes. Due to its excellent properties and sustainability that make it vital to our modern lives, this chemical can be widely used in industry, agriculture and medicine,etc.

What Is Aluminum Sulfate Used For
Iron-free aluminum sulfate is mainly used as paper sizing agent, flocculant for drinking water, industrial water and wastewater treatment, and as raw material for the production of artificial gemstones and other aluminum salts, such as ammonia vitriol, potash vitriol and refined aluminum sulfate. In addition, aluminum sulfate is also widely used in the production of clarifiers, petroleum deodorizing and decolorizing agents, concrete waterproofing agents, paper whitening, titanium dioxide post-film treatment, and catalyst carriers.
