On the basis of thermal analysis kinetic, combining the heating rate for 5°C/ min, 10°C / min and equivalent size separately for 40μm, 55μm and 98μm analyze the calcium carbonate decomposition processes, with different dynamic model and the pervasive computing integral method to solve the reaction kinetics parameters ,according to the principle of the maximum correlation and minimum standard deviation to determine the optimal decomposition mechanism, and it is concluded that the thermal decomposition of calcium carbonate belongs to the phase interface reaction (spherical symmetric). Research found that the same size, with the improvement of the heating rate, activation energy of calcium carbonate reduced, decomposition rate accelerated; in the same heating rate, with the increase of particle size, ore activation energy increase gradually.
