Abstract: The pyrolysates of CoC2O4.2H2O were investigated by TG-DSC and laser granulometry. The results showed that there are three stages in the process of the pyrolytic decomposition of CoC2O4.2H2O in the air. The crystal water in CoC2O4.2H2O was lost from 150℃ to 250℃. CoC2O4 was oxidized into Co3O4 from 250℃ to 300℃. Co3O4 was turned into CoO from 910℃ to 950℃. At the same time, the influence of temperature on the particle size of the decomposition was most from 280.8℃ to 950.0℃. The influence of temperature on the particle size of the decomposition was more from 217.1℃ to 280.8℃. The influence of temperature on the particle size of the decomposition wasn’t obvious from the room temperature to 217.1℃.
