Metallic cobalt nanoparticles are successfully obtained by the pyrolytic decomposition of CoC2O4. 2H2O in the argon gas. The pyrolysates of CoC2O4. 2H2O were investigated by TG-DSC and SEM. The results showed that there are two stages in the process of the pyrolytic decomposition of CoC2O4. 2H2O in the argon gas. The crystal water in CoC2O4. 2H2O was lost from 150 °C to 275 °C. CoC2O4was pyrolysized into metallic cobalt powder from 300 °C to 500 °C. At the same time, the pattern of pyolysate of CoC2O4. 2H2O was fined at 347.7 °C for 10 min. But, the particles of pyolysate of CoC2O4. 2H2O were sintered into cobalt blocks at 500.0 °C for 10 min. Therefore, the conditions of pyrolytic decomposition of CoC2O4. 2H2O were controlled if single cobalt powder was obtained at 500.0 °C..
