hydroksiapatiitit
Hydroksiapatiitit, known in English as hydroxyapatites, are a family of calcium phosphate materials with the idealized formula Ca10(PO4)6(OH)2. They occur naturally as the mineral hydroxyapatite and are produced synthetically for a range of biomedical applications. In biology, bone mineral and tooth enamel contain a non-stoichiometric, carbonate-substituted form of hydroxyapatite, commonly referred to as biological apatite.
Structure and substitutions: Biological apatite typically includes carbonate and trace ion substitutions (such as Na+, Mg2+,
Properties: Hydroxyapatite is biocompatible and bioactive, supporting bone cell attachment and growth. It is osteoconductive, providing
Production and forms: It can be synthesized by wet chemical precipitation from calcium and phosphate precursors
Applications: Hydroxyapatite is used as bone graft substitutes, dental coatings for implants, and as coatings on
