Features:
Hydroxyapatite composition and crystal structure of theoretical composition of hydroxyapatite Ca10 (PO4) 6 (OH) 2, Ca / P of 1.67, but due to the influence of the preparation process, the real composition is quite complex. HA hexagonal crystal, is L6PC symmetric and P63 / m space group, the structure of a hexagonal prism, with the c axis perpendicular to the plane is a hexagon, a, b-axis angle of 120 º;, its lattice parameters is a = 9.43 ~ 9.38Å;, c = 6.88 ~ 6.86Å;, z = 2, unit cell contains 10 Ca2 +, 6 PO43-and two OH-. HA ceramic surface has a surface of several possible states: (1) When a crystalline surface OH, OH with 2 Ca (Ⅱ) ion is connected, when the HA in aqueous solution, the position of this surface at least in a moment OH vacancy , by two Ca (Ⅱ) ion with a positive charge, forming a suction position, this position can be adsorbed PO43-or phosphate groups on the macromolecule or a carboxyl group. (2) When the Ca ions in the surface of the crystal, since Ca (Ⅰ) and 6 charged negatively charged O atom, when the HA in aqueous solution, the surface of Ca (Ⅰ) position vacancies in a moment, in Ca (Ⅰ) position to form a strong adsorption sites, can absorb Sr3 +, K + and other cations and the group of protein molecules, and in the Ca (Ⅱ) position is the formation of a weaker adsorption sites. (3) PO43-in crystal surface, H2O through hydrogen bonding with PO43-ions.2. From the chemical composition in terms of calcium hydroxyapatite is constituted, these two components are the most common constituent of bone tissue and bone tissue is a crystalline calcium hydroxyapatite and phosphate amorphous form, thus hydroxyapatite stone bone substitute material, not only in composition, but also in the structure of human bone tissue is consistent with calcium, it can be used in artificial joints, bone substitute.
3. The bio-ceramic materials, clinical application of artificial joint, bone substitute, toothpaste, food and other applications.
