Resumo

A procedure is proposed for an analysis of the data on the decomposition of inorganic carbonates (MgCO₃, CaCO₃, SrCO₃, MnCO₃, CoCO₃) on the basis of results of thermogravimetric studies. The activation energy and the rate constant for carbonate decomposition are calculated taking into account the main points of the heterogeneous reaction kinetics. A comparative analysis of the obtained results is performed.
