Perovskite Sm1-xSrxCoO3 ceramics have been successfully prepared by gelcasting from oxides and carbonate powders, which were characterized by sintering the gels cast from a suspension of low-solubility metallic oxide precursors and organic monomers. The porosity, pore size, microstructure and electrical conductivity of the obtained Sm1-xSrxCoO3 ceramics were also investigated. It has been shown that single Sm1-xSrxCoO3 perovskite phase forms at a relatively low calcination temperature of 1000°C. Especially, porous Sm1-xSrxCoO3 ceramics with homogeneous microstructure can be obtained by controlling sintering process of the gelcasts. In addition, the Sm1-xSrxCoO3 ceramics show good electrical conductivity, which can meet the demand for solid oxide fuel cell cathode application.
