摘要

(Nd_1-xGd_x)₂(Ce _1-xZr_x)₂O₇ (0 ≤ x ≤ 0.5) ceramic powders synthesised by the chemical-coprecipitation and calcination method were pressureless-sintered at 1,973 K for 10 h in air. The structure and electrical conductivity of (Nd_1-xGd_x) ₂(Ce_1-xZr_x)₂O₇ ceramics were investigated by the X-ray diffraction and impedance spectroscopy measurements. (Nd_1-xGd_x)₂(Ce _1-xZr_x)₂O₇ (0 ≤ x ≤ 0.5) ceramics exhibit a single phase of defect fluorite-type structure. The electrical conductivity of (Nd_1-xGd_x) ₂(Ce_1-xZr_x)₂O ₇ ceramics increases with temperature in the range 623-1,173 K following an Arrhenius law. At identical temperature levels, the measured electrical conductivity of (Nd_1-xGd_x) ₂(Ce_1-xZr_x)₂O ₇ ceramics varies with doping different Gd₂O₃ and ZrO₂ contents and exhibits a maximum at x = 0.1.
