Abstract
The thermal decomposition of basic nickel carbonate (BNC) was investigated using TG-MS. It was found to proceed in two steps, and H2O and CO2 evolved during each step. Measurement of the apparent activation energies of the evolving H2O and CO2 showed that those during the second step were about twice those during the first step. These results indicate that CO2 evolving from BNC during the first step is in a state such as coordinated water.
