aluminum phosphate

Aluminum phosphate is an inorganic compound with the formula AlPO₄, typically appearing as a white, odorless crystalline solid. It is widely used in medicine as an antacid to neutralize stomach acid and relieve symptoms of gastric ulcers and hyperacidity. In addition, it serves as an immunologic adjuvant in vaccines to enhance immune response. Aluminum phosphate’s mechanism of action as an antacid involves direct chemical neutralization of gastric hydrochloric acid, while its role as a vaccine adjuvant is attributed to its ability to stimulate the immune system and improve antigen presentation. Beyond pharmaceuticals, it finds applications in ceramics, dental cements, pigments, corrosion inhibitors, molecular sieves/catalysts for industrial processes, and food additives (as a leavening agent)[1][2][3][4][5].
