The pyrolysates of NiC2O4. 2H2O in the air were investigated by TG-DSC, SEM and TEM. The results showed that there are two stages in the process of the pyrolytic decomposition of NiC2O4. 2H2O in the air. The crystal water in NiC2O4. 2H2O was lost from 175 °C to 275 °C. NiC2O4 was pyrolysized into NiO from 325 °C to 400 °C. In the process of the pyrolytic decomposition of NiC2O4. 2H2O, the influence on the pattern of the decomposition was more from 246.5 °C to 357.8 °C. The influence on the pattern of the decomposition was less from 357.8 °C to 400.0 °C. Therefore, the pyrolytic condition of NiC2O4. 2H2O in the air was controlled if the effective pattern of NiO powder was obtained. At the same time, spherical NiO of about 5 nm is obtianed through the pyrolytic decomposition of NiC2O4. 2H2O at 400 °C for 10 min at the rate of 10 °C / min.
