Electrical Conductivity of Ceria Co-Doped with Zr and Re (Re=La,Y)

摘要：

　　The series of powders with the general formula of Ce0.8-xZrxLa0.2O1.9 (x=0,0.05,0.10,0.15) and Ce0.8-xZrxY0.2O1.9 (x=0,0.05,0.10,0.15) were synthesized by the sol-gel method.The samples sintered at 1500℃ all possess the single phase with cubic fluorite structure.The lattice parameter and the ionic conductivity decrease with increasing the content of Zr.However,the ionic conductivity of ceria co-doped with Zr and La reduces with decreasing the lattice strain.
