Combustion synthesis of La0.7Sr0.3Co0.5Fe0.5O3 (LSCF) porous materials for application as cathode in IT-SOFC

▶ LSCF powders were prepared by the combustion method with different propellants. ▶ Combustion reaction with urea and sucrose is more gradual with better phase formation. ▶ Porosity of sintered pellets decreased with the increase of sintering temperature. ▶ Electrical conductivity is correlated with the sintering temperature.
