Co-doping Effect on Microstructures and Ionic Conductivity of Aliovalent Cations Modified Ceria CHOU Chen-chia1,YEH Tsung-her1 (1.Advanced Ceramics Laboratory, Department of Mechanical Engineering, National Taiwan University of Science and Technology, Taipei-10672, China) 摘要:Microstructural features and ionic conductivity of divalent (Mg2 + ) and trivalent (Gd3 + ) cations co-doped ceria......
The conductivities of rare-earth-doped CeO2 oxides intensely depend on the ionic radii of dopants. For example, the doping of Sm3+ ion, whose ionic radius is the most similar one to the radius of Ce4+, gave the maximum conductivity[7-9]. In this case, it is regarded that the maximum conductivity is due to the similar ionic radius as the host ion resulting in the minimum association enthalpy between......
