    摘要:

    本文采用甘氨酸-硝酸盐法(GNP)和溶胶凝胶法分别合成了Sm0.1Nd0.1Ce0.8O1.9(SNDC) 和La2Mo2O9(LAMOX)粉末,并用常压烧结的方法制备了不同比例的SNDC和LAMOX的复合材料,通过XRD和SEM等手段表征了不同复合比例样品的物相和表面形貌并测试了烧结样品的电导率。结果表明,复合样品的电导率在相变点前后随着复合量增加变化趋势相反,其中LAMOX含量为20mol%的样品在550℃时的电导率能达到0.01S/cm,高于同温度下SNDC电导率。

    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.
