摘　　要：采用硝酸钙、磷酸二氢铵、尿素和双氧水为实验原料,通过无模板的方式在150℃,反应时间为3h的条件下水热合成不同形貌的HAP.利用XRD、FTIR和SEM等测试方法研究原料配比对反应产物的影响.实验结果表明:双氧水的添加对反应产物物相没有影响,为碳酸化的羟基磷灰石;但双氧水的添加促进了HAP纳米片向HAP纳米带或HAP花状结构的转变.HAP with different microstructure have been synthesized via a template-free hydrothermal process,using Ca（NO3）2·4H2O,NH4H2PO4,urea and hydrogen peroxide as the experimental materials,and the reaction temperature and time were fixed at 150 °C and 3h,respectively.The obtained samples are characterized by evaluating XRD patterns,FTIR spectrums and microstructure.Experiments show that the addition of H2O2 had not significant effect for phases of synthesized produces,but the addition of H2O2 promoted transformation of HAP nanosheets to the HAP nanobelt or HAP flower-like structure.
