This study has been carried out to investigate the non-isothermal behaviors and kinetic parameter of calcium carbonate by different thermal analysis methods. At the heating rate of /min, the onset calcination temperature, the peak and final temperatures of calcium carbonate were , , and respectively. As the heating rate of the calcium carbonate increased from /min to /min, the peak temperature increased from to . The activation energies of the calcium carbonate calculated by the methods of Kissinger and Freeman-Carroll were 40.15 kcal/mol and 43.47 kcal/mol, respectively.
