Abstract The kinetics of thermal decomposition of cadmium carbonate CdCO 3 and basic zinc carbonate ZnCO 3 ·nZn(OH) 2 and the effect of intensive milling in a planetary ball mill on its parameters, have been investigated. The values of the reaction heat and of the activation energies of thermal decomposition have been determined for both the compounds.
