Product Description:

Calcium phosphate (Ca3(PO4)2, CAS 7758-87-4) is an inorganic salt that exists in several forms, including tricalcium phosphate (TCP) and hydroxyapatite. It is a white, odorless, and tasteless powder that is insoluble in water but soluble in dilute acids. Its primary application is as a pharmaceutical excipient, where it serves as a multifunctional filler, diluent, and binder in tablet formulations. It is also widely used as a calcium and phosphorus supplement in food and beverages, functioning as a nutritional fortifier and anti-caking agent. In the materials sector, it is a key precursor for bioceramics, particularly in the production of hydroxyapatite for bone grafts and dental implants, due to its excellent biocompatibility and osteoconductive properties. Other significant uses include its role as a polishing agent in toothpaste, a leavening agent in baking powder, and a raw material in the manufacture of fertilizers and animal feed supplements. It is generally recognized as safe (GRAS) for consumption but requires appropriate handling to avoid dust inhalation in industrial settings.
