Abstract: A series of nanocrystallite perovskite-type LaCoO3 were prepared by coprecipitation method using oxalic acid as precipitant. The results of DTA, TGA, XRD and TEM observations showed that the drying condition causes a significant effect on the structure and formation mechanism of the products.
