| Abstract: | In this dissertation,Strontium doped LaMnO3,Ce0.8Sm0.2O3（SDC） and La0.6Sr0.4Co0.2Fe0.8O3（LSCF）powders were prepared by gel-casting process.After sintering at different temperature,both the property and microstructure of sintered samples were characterized.The results showed that the cathodes materials powder formation the perovsikite-phase at 750 ℃,1 200 ℃.The relative density of sample increased with the sintering temperature and the open porosity decrease. |
