摘要

Samples of (Ce _0.8Y _0.2-x Nd _xO _1.9) _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 (Ce _0.8Y _0.2-x Nd _xO _1.9) _0.99(ZnO) _0.01 series samples can be obtained after sintered at 1350°C with 1mol% ZnO. Among all the samples, (Ce _0.8Y _0.05 Nd _0.15O _1.9) _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)×10 ^-6/K.
