研究了分散第二相α－Al2O3对LiAgSO4的离子导电性的影响，发现LiAgSO4－α－Al2O3的电导率随α－Al2O3含量的增加而升高，在300～500℃间电导率高于纯LiAgSO4，α－Al2O3含量摩尔比约为40时最高．TG－DTA和XRD分析表明，在高温稳定的体心立方LiAgSO4降温后以Ag2SO4的正交β相形式存在，但在H2O存在下，生成Li2SO4·H2O和Ag2SO4．FT－IR分析证实，在α－Al2O3与硫酸盐之间没有发生明显的化学反应．H2浓差电池测试结果表明，该材料具有质子导电性，但由于高温下Ag2SO4被H2还原使材料不稳定，故不能在强还原气氛下使用．
The effect of dispersed second phase α-Al2O3 on the ionic conductivity of LiAgSO4 was investigated. The results show that the conductivity of LiAgSO4-α-Al2O3 increases with the increase of α-Al2O3 content. The conductivity of LiAgSO4-α-Al2O3 is higher than that of pure LiAgSO4 , Α-Al2O3 content of about 40 when the molar ratio of the highest. TG-DTA and XRD analysis showed that Li2SO4 · H2O and Ag2SO4 were formed in the orthorhombic β phase of Ag2SO4 after the high temperature stabilized body-centered cubic LiAgSO4 was cooled down. FT-IR analysis confirmed that there was no significant chemical reaction between α-Al2O3 and sulfate. H2 concentration battery test results show that the material has proton conductivity, but due to high temperature Ag2SO4 by H2 reduction of the material instability, it can not be used in a strong reducing atmosphere.
