Gd and Tb co-doped Ce0.8Gd0.2−xTbxO2− (0 ≤ x ≤ 0.09) nanopowders were synthesized by the combustion method using aspartic acid as fuel. The calcined powders formed a ceria-based single phase with a cubic fluorite structure. In addition, the powders were pure, homogeneous, and nanocrystalline nature, i.e., 20.1–23.4 nm in the calculated crystallite size. The partial incorporation of Tb for Gd caused a decrease in the average grain size of the sintered bodies. The high-quality nanosized Ce0.8Gd0.17Tb0.03O2− powders provided a high density, ultra-fine grain size, and high electrical conductivity even at the low sintering temperature of 1300 °C. The grain size and density of the Ce0.8Gd0.17Tb0.03O2− were ∼146 nm and ∼99% of the theoretical density, respectively, allowing enhanced electrical conductivity (0.106 Scm−1 at 800 °C).
