【摘要】 通过添加不同有机模板剂,采用均相沉淀法,制备了粒状、柱状、晶须状、片状、多孔状羟基磷灰石(HAP)。利用TEM及SEM对其晶体形貌进行了表征,结果表明:不同有机模板剂的氢键作用能力对HAP六方柱面m{1010}、平行双面c{0001}、六方锥面o{1011}表面能的影响决定了这些晶面的相对发育程度,从而实现了HAP晶体形貌的控制生长。更多还原

【Abstract】 Granular,cylinder,whisker,flake and porous hydroxyapatites(HAP) were synthesized by template-mediated/homogeneous-precipitation.Crystal morphologies were characterized by TEM and SEM.The results suggested that the hydrogen bond energy between the template and HAP affected the interface free energy of m、c、o,then affected the relative growth degree of these crystal surfaces,and sequentially controlled HAP crystal morphology.更多还原
