Abstract

Hydroxyapatitc (HAp) nanopowders were synthesized using two different chemical precipitation routes. The HAp powders heated at 1000°C showed different amount of β-TCP phase formation most probably due to the difference in chemical homogeneity of precipitated particles. The Ca/P ratio in powder preparation was changed and the amount of HAp and β-TCP phase was analyzed using quantitative x-ray diffraction (Q-XRD). The powder with Ca/P ratio of 1.70 showed the lowest β-TCP content, while that of 1.75 showed formation of CaO phase as well as β-TCP. By changing chemical compositions sintering and β-TCP phase formation behavior of HAp powder could be controlled for the artificial hard tissue applications.
