Modeling chemical kinetics in solid state reactions

Abstract

This work deals with the kinetics of thermally stimulated processes which take place in the solid state phases. The activation energy of the solid is calculated using several methods of different families of isoconversional methods (differential, integral and incremental). A model of the kinetics is obtained by a method independent from the procedure used to compute the activation energy and it is analysed in three theoretical simulations as well as the thermal degradation of FeNH4(HPO4)2. The reconstructed α − T curves of the simulations and the experimental case indicates that the model works properly.
