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.
Pseudo-ternary phase diagrams in quaternary microemulsion systems of cetyltrimethyl ammonium bromide(CTAB), n-butanol, n-octane and water\[or NH_4F solution, or Ba(NO_3)_2 solution, KNO_3-Mg(NO_3)_2 mixture solution\] 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. KMgF_3 nanoparticles were prepared with the optimal parameter of phase diagrams of microemulsions systems.
