Article Preview

Ceria-based solid electrolyte was prepared by low-temperature combustion method, and the synthesis technology was discussed. It can be found that the advantages of choosing citric acid as reducing agent were higher yield and easier reaction control. The crystalline growth of samples was tended to complete when the pre-sintering temperature was 700°C. There was not stratification phenomenon when the forming pressure was 400 MPa. Nano-scale powders were obtained by this way, which caused decreasing of sintering temperature. The effects of Ce0.8Gd0.2O2-δ (CGO) doped manganese oxide as sintering additive on density and conductivity were studied. The relative density of CGO doped 2.0 mol% MnO1.333 (2Mn-CGO) increased within a certain temperature range because of the occurrence of viscous flow sintering. The conductivity measured at 700 °Cof 2Mn-CGO sintered at 1100 °C was 4.52×10-2 S/cm, which is higher than that of CGO.
