The solid solutions Ce0.9RE0.1O2-δ(RE=Pr, Nd,Sm, Gd, Dy) were prepared by sol-gel method. The XRD measurement shows that the solid solution is crystallized in cubic fluorite-type structure and the cell volume of Ce 0.9RE0.1O2-δ decreases with the increase of atomic number of RE. The ionic conduction for Ce0.9RE0.1O2-δ was meas ured by impedance spectroscopy and Ce0.9Pr0.1O2-δ has better conductivity. The linear thermal expansion of Ce0.9RE0.1O2- δ decreases with the increase of atomic number of RE.
