摘要：ZnxSm0.16Ce0.84-xO1.92-x (0 <= x <= 0.1) oxides were prepared by solid state reaction. Zn as sintering additive and dopant was investigated. Zn can be doped into the fluorite structure at x <= 0.04, and at x = 0.1 the secondary phase ZnO can be identified. The sintering activity increased with increasing of x. At 1200 degrees C, the relative density runned up to 95% at x >= 0.02, while the relative density of Zn-free composition reached only 75%. In order to get the relative density above 95%, the Zn-free sample need to be sintered at 1400 degrees C. The conductivity can also be improved by appropriate Zn doping.
