摘要
Abstract
Samples of (Ce0.8Y0.2-xNdxO1.9)0.99(ZnO)0.01(0≤x≤0.2) were synthesized by EDTA-citrate complexing method. The samples were characterized by thermogravimetric, X-ray diffraction, thermal expansion measurement and AC impedance spectroscope, respectively. The effect of Y/Nd dopant ratio on the electrical properties of materials was studied particularly. The results show that all samples prepared by EDTA-citrate complexing method have single cubic fluorite structure. The relatively dense(Ce0.8Y0.2-xNdxO1.9)0.99(ZnO)0.01 series samples can be obtained after sintered at 1350°C with lmol% ZnO. Among all the samples, (Ce0.8Y0.2-xNdxO1.9)0.99(ZnO)0.01 shows the highest ionic conductivity of 58.79 mS/cm measured at 750°C. The thermal expansion coefficients of all samples are in the range of (11.83-12.30)×l0-6/K.关键词
