摘要： 绘制了十六烷基三甲基溴化铵(CTAB)/正丁醇(n-C4H9OH)/正辛烷(n-C8H18)/水[或NH4F溶液、或Ba(NO3)2溶液、或KNO3-Mg(NO3)2混合溶液]四组分微乳体系的拟三元相图.观察了电导率随水(或盐溶液)含量变化的规律,很好地印证了微乳液体系的相行为.选取相图中微乳区点作为最佳条件,制备了KMgF3纳米粒子.

关键词: 微乳液, 电导率, 氟化物纳米粒子

Abstract: Pseudo-ternary phase diagrams in quaternary microemulsion systems of cetyltrimethyl ammonium bromide(CTAB), n-butanol, n-octane and wateror NH4F solution, or Ba(NO3)2 solution, KNO3-Mg(NO3)2 mixture solution are presented. Variation of the electrical conductivity with the change of water content(or solution) was observed, which supported the phase behavior of microemulsion systems. KMgF3 nanoparticles were prepared with the optimal parameter of phase diagrams of microemulsions systems.

Key words: Microemulsions, Conductivity, Fluoride nanoparticles
