Abstract：Electrolyte materials Ce_0.8Sm_0.2O_1.9were synthesized via hydrothermal method at a temperature range of 120 to 180 ℃. The electrolyte powders and sintered samples were characterized by XRD、SEM and AC impedance, respectively. The average grain sizes are about 13 nm and the powders synthesized at 140 ℃ have the better sinterability and higher ionic conductivity.

Keywords: hydrothermal synthesis; electrolyte; CeO₂; conductivity
