Characterization of nano-scaled calcium phosphate particles made using microwave assisted synthesis

초록

By instant microwave assisted synthesis, nanocrystalline hydroxyapatite was prepared that was rod-like shaped 42.3 +/- 1.3 nm in length with a diameter of 15.3 +/- 0.4 nm. The results from analysis such as thermogravimetric analysis, wide-angle X-ray diffraction, energy dispersive X-ray spectroscopy, and transmission electron microscopy indicated that the fabricated powders coincided with hydroxyapatite in nature. In addition, it was found that the BET specific surface area and the adsorption average pore diameter of the nanocrystalline hydroxyapatite powders obtained by this easy microwave assisted synthesis were 94.3 +/- 0.6 m(2)/g and 18.8 nm, respectively.
