    Abstract:

    glycine-nitrateSprocessS(GNP) and Sol-Gel method are used to synthesis Sm0.1Nd0.1Ce0.8O1.9(SNDC) and La2Mo2O9(LAMOX)powders, respectively. Different ratio of SNDC/LAMOX composites were fabracated through pressureless sintering. XRD and SEM were used to characterize the material phase and morphology of the samples with different composition. The conductivity of samples were test and the result shows an reverse trend with La2Mo2O9 amount near the phase transformation point. The conductivity of sample with 20mol% LAMOX reaches 0.01S/cm at 550℃, higher than that of SNDC at the same temperature.
