Background Technology Of Hydroxyapatite

Hydroxyapatite [HA][Ca10(PO4)6(OH)2] belongs to the phosphate-based inorganic non-metallic materials. Its chemical composition and crystal structure are very similar to the mineral composition of vertebrate bones and teeth. After implantation into the human body, it forms an organic bond with living tissue through biochemical reactions on its surface, exhibiting good biocompatibility and affinity, making it an ideal active bioceramic material. It is generally used as a matrix or reinforcement for active bioceramics, metal-based or glass-based biomaterial coatings, and biocomposite materials. Because hydroxyapatite also has a strong ability to absorb chemical substances, it can absorb toxic cations in wastewater and can also be used as a catalyst carrier, drug release carrier, etc.
