| 摘 要： | In the paper, nano-hydroxyapatite was synthesized by hydrothermal treatment. The erystal morphology and compositions of the synthetic HA were investigated using TEM,IR, XRD and XPS techniques and were compared with those of porcine femoral bone apatite. The results showed that the synthetic HA is nanometer rod crystal similar to the bone apatite, and the average crystal sizes calculated by Scherrer equation for the four samples (HA dried at 80℃, unburned bone apatite, HA calcined at 750℃ and bone apatite calcined at 750℃ )are 20.6, 21.7, 22.5 and 27.6nm ,respectively, Moreover, the essential compositions for the synthetic HA and bone apatite are almost the same.
