以水合硝酸钙和磷酸二铵溶液为原料，采用沉淀法和热处理法制备了羟基磷灰石微粉。采用傅里叶变换红外光谱(FTIR)、X射线衍射仪(X射线衍射仪)和同步热分析(STA)等手段对样品的结构演化进行了研究。利用透射电子显微镜和扫描电子显微镜对粉末的粒度进行了表征，并对粉末的形貌和团聚状态进行了观察。结果表明，以原料为原料，采用沉淀法可以成功制备出羟基磷灰石纳米晶。当温度从100摄氏度升高到1200摄氏度时，羟基磷灰石颗粒逐渐增大，并且在1200摄氏度之前，羟基磷灰石六方双锥相未转变为其他钙磷酸盐相。(C)2006 Elsevier B.V.保留所有权利。
In this investigation, hydroxyapatite powder has been synthesized from the calcium nitrate hydrated and di-ammonium hydrogen phosphate solution by precipitation method and heat treatment of hydroxyapatite powders. In order to study the structural evolution, the Fourier transform infrared spectroscopy (FTIR), the X-ray diffraction (XRD) and simultaneous thermal analysis (STA) were used. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) were used to estimate the particle size of the powder and observe the morphology and agglomeration state of the powder. Results show that hydroxyapatite nanocrystalline can successfully be produced by precipitation technique from raw materials. Hydroxyapatite grain gradually increased in size when temperature increased from 100 to 1200 degrees C, and the hydroxyapatite hexagonal-dipyramidal phase was not transformed to the other calcium phosphates phases up to 1200 degrees C.
