Abstract:

Article Preview

Surface and porous characteristics of spray dried hydroxyapatite microspheres were studied by surface area and pore size analyzer, field-emission scanning electron microscope, Fourier transform infrared spectroscope, etc. The results indicated dehydration did not happened for those samples calcined at 1000°C, and the intensity of OH- absorption bands increased. Hydroxyapatite microspheres were composed of near-spherical crystals with the diameter of 20-50nm. Besides, it was interesting to find that hydroxyapatite crystals formed small aggregate firstly during drying, and then the small aggregate united together and formed particles with spherical structure.
