摘要: 为研究高温烧结羟基磷灰石靶的细胞相容性,把纯度为99%的羟基磷灰石粉末压制成圆盘形靶,在氩气中在800℃高温下烧结成型。用X射线衍射仪和X射线光电子能谱仪对羟基磷灰石靶的结构组成进行检测。用四氮唑盐比色法对羟基磷灰石靶的细胞相容性进行检测。检测结果表明:纯度为99%的羟基磷灰石粉末在压制成型和800℃高温烧结的过程中化学组成没有发生变化,羟基磷灰石靶中的平均粒径为78.2nm、结晶度为89.4%、Ca/P比值为1.592,具有很好的细胞相容性。

Abstract: In order to study cellular compatibility of hydroxyapatite(HA) target sintered at high temperature, the powder of 99% pure hydroxyapatite was pressed to discal targets and the targets were sintered at 800℃ in argon ambience. The microstructure and composition of targets were detected with X-ray diffractometer(XRD) and the X-ray photoelectron spectroscopy(XPS). The cellular compatibility of targets was detected with Methyl Thiazolyl Tetrazolium(MTT). The experimental result demonstrates the chemical composition of targets was not changed while the powder of hydroxyapatite was pressed to targets and the targets were sintered at 800℃ in argon ambience. The average particle diameter in target was 78.2nm, the crystallinity in target was 89.4% and the ratio of Ca to P in target was 1.592. The hydroxyapatite target sintered at 800℃ had cellular compatibility.

Key words: materials, hydroxyapatite target, sintering at high temperature, ratio of Ca to P, cellular compatibility
