摘　　要：以饱和氢氧化钙上清溶液、磷酸为主要原料,在室温,pH值为9,反应时间6小时条件下,采用共滴定法制备纳米级羟基磷灰石,并通过XRD、TEM、IR检测等测试手段对材料进行分析表征。结果表明:材料中的羟基磷灰石为类似于自然骨矿物相结晶度低的含微量碳酸根的纳米晶体,制备的六方晶型纳米羟基磷灰石长轴约为80nm,短轴约为30nm,粒径均匀且分散性较好。Nano-hydroxyapatite particles were synthesized from the supernatant of saturated Ca （OH）2 solution and phosphoric acid by simultaneous titration at room temperature, PH=9 and reaction of 6 hours, and the properties of the materials were characterized by means of XRD, TEM, IR. The results show, the HAP synthesized was poorly crystallined nanometer crystals slightly carbonated, homogenous particles with good dispersion are hexahedron hydroxyapatite, the average major axial diameter of the particle is about 80 nm and the average minor axial diameter is about 30 nm.
