The solid solutions Ce_(0.9)RE_(0.1)O_(2-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_(0.9)RE_(0.1)O_(2-δ) decreases with the increase of atomic number of RE. The ionic conduction for Ce_(0.9)RE_(0.1)O_(2-δ) was measured by impedance spectroscopy and Ce_(0.9)Pr_(0.1)O_(2-δ) has better conductivity. The linear thermal expansion of Ce_(0.9)RE_(0.1)O_(2-δ) decreases with the increase of atomic number of RE.

The XRD measurement shows that the solid solution is crystallized in cubic (0) O_ (2-δ) decreases with the increase of atomic number of RE.
