| 摘 要： | 用水热合成方法在不同条件下制备了纳米级磷灰石晶体。结果表明：磷灰石晶体含有0H^-、CO3^2-、Na^ 、HPO4^2-离子；水热合成时温度越高，反应时间越长，磷灰石结晶度越高，晶体生长得更大更长；磷灰石沉积物老化时间越短，表面活性越高，水热处理时更容易生长成较大的晶体；压力条件下水热处理后的磷灰石晶体呈棒状，常压下水热处理的呈针状，且长径比较大。

| Abstract: | Nano-apatite crystals were prepared by hydrothermally synthesized method under different conditions. The results indicate that the nano-apatite crystals contain OH- , CO32- , Na+ and HPO42- ions; the size and crys-tallinity of the nano-apatite crystals increase with the increasing of hydrothermal temperature, treatment time, surface activity of apatite precipitation; the nano-apatite morphology is rod-like under pressure and needle-like with a bigger aspect ratio under normal pressure. |
