Fund Project: The authors gratefully acknowledge financial supports from the National Natural Science Foundation of China (Grant No.59789201), the National Advanced Materials Committee of China (Grant No.715-006-0122) and the Ministry of Science and Technology, China (Grant No.G1999022401).

CO₂-TPD was demonstrated an effective way to investigate the phase formation during pyrolysis for the preparation of composite oxides using metal-organic molecules as precursors. Based on the CO₂-TPD results, it was found that calcination condition had deep effect on the carbonate formation and the minimum firing temperature to acquire pure phase composite oxide. An optimized calcination schedule was then developed.
