【摘要】 采用硝酸钙和磷酸铵为反应前驱物,通过水热合成颗粒尺寸在100nm以下的短棒状或针状羟基磷灰石晶体。X射线衍射(XRD)、透射电镜(TEM)和红外光谱(FTIR)分析讨论水热温度、反应时间、表面活性剂和烧结与物相组成、晶粒尺寸和晶体形貌的关系。更多还原

【Abstract】 Hydroxyapatite powders（HA） were hydrothermally synthesized by using Ca(NO₃)₂·4H₂O and ((NH₄)₃PO₄·3H₂O) as raw materials in an autoclave . Hydroxyapatite crystals was needle like or column like . The particle size was to be very fine and less than 100 nm. The relation between hydrothermal temperature,reaction time, surface active agent and the resultant phases, crystal grain size, crystal morphology was analyzed by X-ray diffraction（XRD）,Transmission electron micrograph（TEM） and Fourier transform infrared spectroscopy（FTIR）.更多还原
