LaCoO3 is a typical ABO3 perovskite-type compounds. It has excellent chemical stability and good e-lectrical conductivity under high temperature,due to their potential applications in energetics both as cathodes and solid electrolytes in solid oxide fuel cells,and both in environmental catalysis for pollutant decomposition and colossal magnetoresistance materials. Found by XRD and XPS studies,the best ratio of synthesis of LaCoO3 by solid-phase sintering method is Co La=105%,the optimum sintering time of 50 hours.
