Hydroxyapatite Cas 1306-06-5

Hydroxyapatite, abbreviated as HAP, is the most widely used crystalline phase of calcium phosphate salts. Calcium phosphate salts are the main mineral components of vertebrate bones and teeth. Among calcium phosphate salts, hydroxyapatite is the thermodynamically stable crystalline phase of calcium phosphate salts in body fluids, and is most similar to the mineral parts of human bones and teeth. The ratio of calcium and phosphorus elements in hydroxyapatite is influenced by the synthesis method, and the calcium phosphorus ratio is not fixed, making its composition relatively complex.
