This paper reports on a novel sol-gel technique for synthesis phase pure hydroxyapatite Ca₁₀(PO₄)₆(OH)₂ powder. Triethyl
phosphite and calcium nitrate were used as phosphorus and calcium precursors, when the stoichiometric Ca/P ratio 1.67 was
maintained. The powders obtained were dried and calcined at different temperatures up to 900°C. X-ray diffraction analysis
and Raman spectra showed the presence of phase pure HAP. The powders exhibited the FT-IR signature peaks of HAP. In
addition, morphological characterizations of the HAP powder was carried out using STEM, EDXS and EELS. The STEM
micrographs indicated mill-fractured surface of a HAP particles. The elemental composition analyzed by EDXS and EELS
showed the powder calcined at 900°C contains monophasic stoichiometric HAP. |
