摘　　要：用Triton X-100／正己醇/环己烷/水四元反相微乳液体系制备了纳米羟基磷灰石（HA）粉体，确定了影响制备过程的最佳pH值和煅烧温度等工艺条件。x-射线衍射仪、TEM、SEM对羟基磷灰石的颗粒进行表征和分析表明：颗粒分散均匀，呈杆状，a轴尺寸为20～40nm左右，c轴尺寸为60～80nm,此方法可以有效地控制和改变HAP的分散性和粒度大小。The monodispersive nano-hydroxyapatite particles were prepared by the microemulsion solutions of Triton X-100/Hexanol/ Cyclohexaneane/water system and characterized by XRD, IR, SEM and TEM. The effects of pH value of microemulsion solutions and sintered temperature on the morphology and size of HA particle were investigated. The optimum synthetic process is pH = 10, sintered temperature is 750℃. The results indicate that the growing habit and particle size can be controlled effectively.
