Aluminum sulfate, Al2(SO4)3, is typically found in a white, crystalline powdered form. It is commonly known as alum or aluminate. It includes over 17% alumina (Al2O3) and is produced from sulfuric acid and aluminum trihydrate. Aluminium sulfate is also obtained as an 18-hydrate Al2(SO4)3.18H2O. Both forms are non-toxic, soluble in water, and non-combustible. Aluminum sulfate is widely used in various industries and applications due to its unique properties.
