| 摘 要： | 为研究烧结温度对羟基磷灰石靶的影响规律，把纯度为99%的羟基磷灰石粉末压制成圆盘形靶后，在氩气中分别在600℃、700℃和800℃高温下进行烧结。用X射线衍射仪和X射线光电子能谱仪对未烧结和不同温度下烧结的羟基磷灰石靶进行检测。检测结果表明：烧结温度对羟基磷灰石靶的结晶度和组成元素没有显著影响。但是随着烧结温度的升高，羟基磷灰石靶的平均粒径和钙磷比值都增大。800℃高温烧结的羟基磷灰石靶将具有更好的生物相容性、生物活性和稳定性。

| Abstract: | In order to find out rule for sintering temperature to influence hydroxyapatite(HA) target, the powder of 99% pure hydroxyapatite was pressed to discal targets and the targets were sintered at 600℃, 700℃ and 800℃ in argon ambience respectively. The targets stinered at different temperature and the targets not sintered were detected with X-ray diffractometer(XRD) and the X-ray photoelectron spectroscopy(XPS). The experimental result demonstrates sintering temperature did not influence on the composition and crystallinity of all kinds of targets observably, but the average particle diameter and the ratio of Ca to P of hydroxyapatite targets should increase if sintering temperature rised. The hydroxyapatite target sintered at 800℃ should have the best biocompatibility, bioactivity and stability. |
