摘　　要：羟基磷灰石 (HA)已广泛用作人体硬组织的修复和替换材料 ,采用冲击波处理CaCO3与CaHPO4·2H2 O的混合物合成了HA粉末 ,并用XRD、SEM和FTIR对制得的粉末进行了表征。研究结果表明 :与传统的高温焙烧法相比 ,用冲击波法合成的HA粉末不仅有类似的晶相结构及成分 ,而且含有少量CO2 -3 离子 ,为类人骨的羟基磷灰石 ;其粒度更细、分布更均匀、内部存在大量的晶格畸变 ,有更高的活性。冲击波处理是合成HA粉末的一种新方法。Hydroxyapatite(HA) is an effective materials used in bone prostheses.HA powders were prepared in the present paper by shock-loading the mixture of CaCO 3 and CaHPO 4·2H 2O.The prepared HA powders were characterized by XRD,SEM,and FT-IR.It is shown that HA powders prepared by shock wave treatment are similar to those prepared by calcinations in structure and components,and contain CO 2- 3 ions.HA powders have smaller and uniform grain size,and much higher activity because of the existing of strain and dislocation defects of crystals.It is believed that the method of shock wave treatment may be a new method for preparing HA powders used as a kind of biomaterials.
