Fabrication and Conductivities of CeO2-based Oxygen-ion Conductors Doped by M2O3 (M=La,Nd,Sm and/or Ga)

摘要：

　　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 ℃ 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.
