abstract
In this study, Na+- and CO32--containing hydroxyapatites (NCAps) and K+- and CO32-- containing hydroxyapatites (KCAps) were prepared by the hydrolysis of monetite in solutions with independently varied CO32- and alkalimetal (M(+)) concentration. The chemical and physical analysis results show that both the CO32- and the M(+) incorporation in apatite can affect the dimensions of the hexagonal lattice. From the composition of the unit cell of these apatites, the contributions of the substitution mechanisms for the incorporation of CO32- and M(+) could be calculated. Generally, the contributions of the predominant mechanisms, (Ca2++PO43-+OH-<->V-Ca+CO32-+V-OH) and (Ca2++PO43-<->M(+)+CO32-) with V-X a vacancy on a regular X lattice site, vary as can be expected on the basis of the variation of the driving force in the hydrolysis solution. Their behavior seems to suppress the appearance of the less stable mechanisms: (Ca2++OH-<->M(+)+V-OH) for the NCAps and (Ca2++2PO(4)(3-)<->V-Ca+2CO(3)(2-)) for the KCAps. This suggests that, although there is no intrinsic coupling between the fundamental substitution mechanisms, an indirect correlation can occur.
