The theoretical composition of hydroxyapatite is CA*0 (PO4) 6 (OH) 2 and Ca / P is 1.*7. However, due to the influence of preparation process, its real composition is quite complex. HA crystal belongs to hexagonal system, belongs to l6pc symmetry type and p*3 / M space group. Its structure is hexagonal column, and the plane perpendicular to c axis is a hexagon with an angle of **0 ° between a and B axes. Its unit cell parameters are a = 9.*3 ~ 9.*8 , C = 6.*8 ~ 6.*6 , z = 2. The unit cell contains *0 Ca2 +, 6 PO*3 - and 2 Oh -. There are several possible surface states on HA microcrystalline surface: (1) when Oh is located on the crystal surface, oh is connected with two Ca (â…¡) ions. When HA is in aqueous solution, the oh position on the surface is vacant at least for a certain moment Ca (â…¡) ions are positively charged, forming an adsorption site, which can adsorb PO*3 - or phosphate or carboxyl groups on macromolecules. (2) When Ca ion is located on the surface of the crystal, because Ca (I) is connected with six negatively charged O atoms, when ha In aqueous solution, when the Ca (I) site on the surface is vacant at a certain moment, a strong adsorption site is formed at the Ca (I) site, which can adsorb cations such as SR3 +, K + and protein molecules, while a weak adsorption site is formed at the Ca (II) position. (3) When PO*3 - is located on the surface of the crystal, H2O binds to PO*3 - ion through hydrogen bond.
