摘　　要：制备了两种稳定的CTAB/正丁醇/正己烷/水体系和TritonX-100/正己醇/环己烷/水反相微乳液体系,研究了微乳液组份的浓度和比例对微乳液性质的影响,比较了两种反相微乳液体系的三元相图,用“微反应器”合成了纳米羟基磷灰石(HAP)粉体,比较了HAP颗粒在X-射线衍射、TEM、SEM表征中的异同。两种体系都表明反向微乳液法可以有效地控制和改变HAP的分散性和粒度大小。The two sorts of steady microemulsion solutions of CTAB/ butanol/hexane/ water and Triton X-100//hexanol/ cyclohexaneane/ water system were prepared,and the effects of the concentrations and compositions of CTAB,Triton X-100,hexanol and cyclohexaneane on the microemulsion solutions were studied . On the base of partial ternary phase diagram,the monodispersive nano-hydroxyapatite particles were prepared by the 'microreactor'of microemulsion solutions and characterized by XRD,SEM and TEM.The different between two sorts of inverse microemulsion system for synthesis of nano-hydroxyapatite particles were investigated.All the results indicate that the growing habit and the partical size can be controlled effectively.
