Comparison of Thermal Decomposition Kinetics of Magnesite and Limestone

The thermal decomposition kinetics of magnesite and limestone, which are alkaline earth metal carbonates, were investigated using thermal analysis method. The research results showed that their kinetic decomposition characteristics and apparent decomposition activation energy have the comparability. Based on the thermodynamic/thermogravimetric data, the industrial production process of magnesite and limestone can draw on the experience of each other because of their similar decomposition thermodynamics and kinetics.
