摘要: 为研究烧结时间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,在氩气中保持800℃恒温分别烧结12小时、16小时、20小时和24小时。用X射线衍射仪和X射线光电子能谱仪对不同时间烧结的羟基磷灰石靶进行检测。检测结果表明:烧结时间对羟基磷灰石靶的结晶度和组成元素种类没有显著影响,但对钙磷比值有显著影响。烧结时间从12小时增加到20小时,Ca/P比值增大;从20小时增加到24小时,Ca/P比值反而减小。20小时800℃高温烧结的羟基磷灰石靶将具有更好的生物相容性和稳定性。

Abstract: In order to find out rule for sintering time to influence hydroxyapatite(HA) target, the powder of 99% pure hydroxyapatite was pressed to discal targets and the targets were sintered for 12 hour, 16 hour, 20 hour and 24 hour at 800℃ in argon ambience respectively. The targets stinered at different time were detected with X-ray diffractometer(XRD) and the X-ray photoelectron spectroscopy(XPS). The experimental result demonstrates sintering time did not influence on the composition and crystallinity of targets observably, but sintering time should influence on the ratio of Ca to P of targets. The ratio of Ca to P should increase when sintering time increase from 12 hour to 20 hour, but the ratio of Ca to P should decrease when sintering time increase from 20 hour to 24 hour. The hydroxyapatite target sintered for 20 hour at 800℃ should have the best biocompatibility and stability.
