摘　　要：以四水硝酸钙和磷酸氢二铵为原料,并引入微生物-酵母细胞作为模板,通过化学沉淀法合成了纳米羟基磷灰石(HA)粉体。采用X射线衍射(XRD)、透射电镜(TEM)和热分析(TA)对HA粉体进行了表征分析。结果表明,引入微生物模板后,羟基磷灰石粉在700℃煅烧后的粒度在40 nm以下。This paper introduced the preparation of the nanohydroxyapatite powder via precipitation method by using Ca （NO3）2 ·4H2O and （NH4）2HPO4 as raw materials. The microbial cells were incorporated in the process of HA. The characterization methods such as X-ray diffraction （XRD）, transmission electron microscopy （TEM） and thermal analysis（TA） were used for the determination of the HA particle properties. As a result, even if the HA was calcined at 700 ℃, the size of oowder was below 40 nm.
