Critical study on the identification of reaction mechanism by the shape of TG/DTG curves
چکیده انگلیسی

It was proposed that the reaction mechanism of solid state reactions can be identified based on the asymmetry or shape of TG (Thermogravimetry) and DTG (Differential Thermogravimetry) curves in non-isothermal kinetics in the literature. A flow chart was also designed for the identification of the reaction mechanism by some authors. This paper has revisited this method and revised the flow chart with more reliable values of conversion at the maximum rate and the half width range of the DTG curves. The revised chart is proven to be more reasonable by an example application to identify the reaction mechanism of calcium carbonate decomposition and is recommended to replace the original one.
