【 摘 要 】

The phase behavior of the system employing TritionX-100 as surfactant was investigated with setting different rea-gents as cosurfactant and oil phase at various temperatures and mass ratios of TritionX-100 to cosurfactant. The pseudo-ternary phase diagrams were drawn by using conductivity method. The results indicate that the microemulsion is the most stable and has the best water solubility when the mass ratio of TritionX-100 to hexylalcohol is 1:1. Based on that, LMA powder was synthesized via reversed-microemulsion method using nitrate and ammonia as raw materials. The surface area of LMA powders increases to 53.41m2/g with the increasing water content of the system.
