| 摘 要： | The solid solutions Ce0.9RE0.102-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 Ce0.9RE0.1O2-δ decreases with the increase of atomic number of RE. The ionic conduction for Ce0.9RE0.1O2-δ was measured 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.
