The electrical conduction and microstructure in Y-doped ceria and Ho-doped ceria were investigated. Visible differences between the two doped ceria were observed. The plots of conductivity of Y-doped ceria are well fit to the Arrhenius behavior, while curvature and kinks were observed on the...

Well dispersed Ce1−xTbxO2−δ nano-powders were synthesized by using the carbonate coprecipitation method in an entire compositional range of 0⩽x⩽1, which allowed the preparation of highly dense pellets by sintering at 1673K and the systematical study of the electrical conductivity in...
