초록
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℃/min, the onset calcination temperature, the peak and final temperatures of calcium carbonate were 612℃, 748℃, and 890℃ respectively. As℃he heating rate of the calcium carbonate increased from 5℃/min to 20℃/min, the peak temperature increased from 719℃ to 782℃. The activation energies of the calcium carbonate calculated by the methods of Kissinger and Freeman-Carroll were 40.15 ㎉/mol and 43.47 ㎉/mol, respectively.
