Paper Title:
Fabrication and Conductivities of CeO2-Based Oxygen-Ion Conductors Doped by M2O3 (M=La, Nd, Sm and/or Ga)
  Abstract

Ceria oxygen-ion conductors doped with M2O3 (M=La, Nd, Sm and/or Ga) were prepared by a wet chemical method. Phases were analyzed by X-ray diffraction method and conductivities were measured by using AC impedance analyzer. The results showed that Ga2O3-CeO2 solid solution with 17 nm grains and pure fluorite phase had been obtained even at calcination temperature of 800 °C for 5 hs. Conductivities of Ga2O3-La2O3 co-doped CeO2 were higher than that of Sm2O3-doped CeO2, which was reported having the highest conductivity among CeO2-based oxides.
