采用超声波以CaCl2和（NH4）：HPO4为原料合成纳米羟基磷灰石（HAP），并与沉淀法和加表面活性剂超声法相比较。利用热分析（TG—DSC），红外光谱（FTIR），X-射线衍射（XRD），扫描电镜（SEM）对样品进行了表征，研究了不同方法、不同煅烧温度对HAP组成和结构的影响。实验表明，超声波法合成的HAP呈不规则球形，平均粒径为42．85nm，沉淀法的HAP呈不规则球形和棒状，球形平均粒径为71．42nm，棒状为71．42×85．71nm，比较而言，超声波法的样品粒径均匀，而沉淀法粒径较大且容易团聚。温度高于750℃后，开始失去羟基，在800℃图中明显出现斜方晶系的磷酸钙的XRD峰。

Nano -hydroxyapatite power was prepared via three different methods, ultrasonic irradiation, ultra- sonic irradiation adding surfactants, precipitations, using CaC12 and （NH4 ）2HPO4 as the crude materials. TG- DSC,FTIR,XRD,SEM were used to characterize the synthesized powder. It was investigated that different methods synthesized HAP and the various calcining temperatures of HAP have some influence in the composition and structure of HAP . The results show that the HAP treated by ultrasonic was irregular ball with their average diameter of 42.85nm, but the HAP prepared by precipitation was two kinds of morphology with irregular bails and sticks, the ballg average diameter was 71.42nm, the stickb average size was 71.42 by 85.71nm. In contrast, the HAP with ultrasonic was better than others in distribution, the HAP with precipitation had larger size and gathered easily . When the temperature was higher than 750 C, it would begin to lose hydroxyl, and tricalcium phosphate is genera- ted, and its peaks were obvious at 800 C.
