***ailed description:
The theoretical composition of hydroxyapatite is Ca10 (PO4) 6 (OH) 2, Ca / P of 1.67, but due to the processes of preparation, the real composition is quite complex. HA is hexagonal crystal, is L6PC symmetric and P63 / m ***ce group, its structure is a hexagonal prism, with the c axis perpendicular to the plane is a hexagon, a, b-axis angle of 120o;, its lattice parameters is a = 9.43 ~ 9.38&©|197;;, c = 6.88 ~ 6.86&©|197;;, z = 2, unit cell contains 10 Ca2+, 6xPO43-and 2 of OH-. HA surface has a surface of several possible states: (1) When a crystalline surface OH, OH with 2 Ca (¢ò) ion is connected, when the HA in aqueous solution, the position of this surface at least in a moment OH vacancy , by two Ca (¢ò) 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 (¢ñ) and 6 charged negatively charged O atom, when the HA in aqueous solution, the surface of Ca (¢ñ) position va |
