| description | The present study investigates the chemical composition, solubility, and physical and mechanical properties of carbonate
hydroxyapatite (CO3Ap) and silicon-substituted carbonate hydroxyapatite (Si-CO3Ap) which have been prepared by a simple
precipitation method. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), X-ray fluorescence (XRF)
spectroscopy, and inductively coupled plasma (ICP) techniques were used to characterize the formation of CO3Ap and Si-CO3Ap.
The results revealed that the silicate (SiO4
4−) and carbonate (CO3
2−) ions competed to occupy the phosphate (PO4
3−) site and also
entered simultaneously into the hydroxyapatite structure.TheSi-substitutedCO3Ap reduced the powder crystallinity and promoted
ion release which resulted in a better solubility compared to that of Si-free CO3Ap. The mean particle size of Si-CO3Ap was much
finer than that of CO3Ap. At 750∘C heat-treatment temperature, the diametral tensile strengths (DTS) of Si-CO3Ap and CO3Ap
were about 10.8 ± 0.3 and 11.8 ± 0.4 MPa, respectively. |
