Paper Title:
Preparation of Metal Cobalt Powder by Co-Precipitation and Heat Decomposition Method
  Abstract

A novel chemical precipitation method was studied to prepare the metal cobalt powder from the precursor Co(OH)x(CO3)y powder. From XRD and IR analysis, it was proved that there were interactions between the NH4+, Cl- and the precursor powder of Co(OH)x(CO3)y. Based on DSC-TGA analysis, the influence of additive and temperature on the cobalt powder preparation process was observed during heat decomposition. The results showed that pure metal cobalt was obtained when the amount of the additive tartaric acid was about 60% and calcination temperature was 500°C.
