【摘要】 对溶胶凝胶法制备纳米级羟基磷灰石生物陶瓷粉末的技术工艺进行了探索性研究．研究表明选择合适的原料配比，溶胶液的ｐＨ值、烧结温度和恒温时间，对于提高制备ＨＡ粉末的纯度和结晶度，改善ＨＡ晶体的纳米结构，并形成直径１μｍ左右的团聚体是极为重要的更多还原

【Abstract】 This paper use solgel method to probe into the new tachnique for research and preparing nanometer scale Hydroxyapatite(HA) biocerarmics powder.It is very important to raise purity and degree of crystallization of preparing HA powder,improve HA nanoconstruction and form granule structure of about 1 μm diameter through choosing suitable raw material compound the PH value of sol liquid,sintering temperature and constant temperature time.更多还原
