Abstract:

以磷酸氢二氨[(NH4)2HPO4]、四水硝酸钙[Ca(NO3)2·4H2O]和四水硝酸铅[Pb(NO3)2·4H2O]为原料,在200℃水热处理12h制得Ca10-xPbx-HA[x=0~10,Ca-Pb-Ca10(PO4)6(OH)2,Ca-Pb-hydroxyapatite,Ca-Pb-HA]固溶体。通过X射线衍射、化学分析方法以及电子显微镜对Ca-Pb-HA固溶体的晶相、化学组成和形貌进行了分析。利用Rietveld方法对Ca-Pb-HA固溶体进行了结构精修,结果表明晶体结构随铅离子固溶量的增大发生了较大的变化,晶胞参数a和c不随铅离子含量的变化而呈线形变化。在Ca-Pb-HA固溶体中铅离子优先占据M(2)位置。Rietveld分析结果很好地解释了Ca-Pb-HA固溶体结构随铅离子含量的变化规律。
