采用烧结法制备阴极材料(La0.85Sr0.15)y(Mn1z-Crz)O3(y=0.85;1;z=0.1,0.2).研究了多孔锰酸镧与致密ZrO2(8mol%Y2O3)界面的成分变化和显微形貌(La0.85Sr0.15)(Mn0.9Cr0.1)O3呈现高电子电导率、良好的热膨胀系数匹配和化学稳定性而(La0.85Sr0.15)MnO3未起到阻止界面退化的作用在1300~1500℃范围内Mn、La、Zr和Sr发生扩散,其中Mn的扩散明显
As a cathode materials the compound La0.85Sr0.15MnO3 with substitution of Cr for Mn and substoichiometry at La site was prepared by powder sintering method. The interfaces between porous La0.85Sr0.15 MnO3 layer and dense ZrO2 (Y2O3 )pellets, similar to th
