摘要
用水热法制备出结晶度高、纯净均一的针状羟基磷灰石单晶体。从X 射线衍射谱、红外吸收光谱、透射电镜分析等方面确认了所得晶体为羟基磷灰石单晶体。根据透射电子衍射谱测量计算出的晶面间距d值与羟基磷灰石卡片的d值非常接近 ,由标定的晶面指数计算出的晶面夹角与实际测量值有很好的吻合 。
The needle like hydroxyapatite single crystals with high crystallinity were prepared by homogeneous precipitation method under hydrothermal condition.The obtained specimens were identified by XRD,SEM,IR and TEM.The inter planar distance i.e.,d value calculated from the pattem of TEM,is greatly approached to that of HA’s JCPDS card,and the angle included between the faces of crystals calculated from the marked crystal plane index is coincided with the actual measuring value,thereby it is confirmed that the specimen is single crystal.
