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 $10^{circ}C$/min, the onset calcination temperature, the peak and final temperatures of calcium carbonate were $612^{circ}C$, $748^{circ}C$, and $890^{circ}C$ respectively. As the heating rate of the calcium carbonate increased from $5^{circ}C$/min to $20^{circ}C$/min, the peak temperature increased from $719^{circ}C$ to $782^{circ}C$. 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.
