Ammonium aluminium sulfate; Ammonia alum; Aluminium ammonium sulfate; Ammonium aluminium sulfate dodecahydrate, Tschermigite
Aluminium ammonium sulfate is a versatile double salt widely used in water purification, paper sizing, textile dyeing, and cosmetic formulations. Its ability to precipitate impurities and stabilize emulsions makes it valuable in both industrial and laboratory settings.
Typical applications include water and wastewater treatment, leather tanning, fireproofing textiles, and as a mordant in dyeing processes. It also finds use in food processing (E number E523) as an acidity regulator and in analytical chemistry for precipitation and crystallization tasks.
Product grades should be selected based on end-use requirements, solubility needs, and regulatory standards.
