Solid-state reactions take place by different rate-controlling heterogeneous processes. To find the appropriate kinetic model for a particular solid-state reaction, a genetic algorithm-based simulation technique was carried out using DTA data with a fitness function, and a computer program was developed for the same. The process was applied to the decomposition reactions of limestone and magnesite samples. It was observed that both the decomposition reactions mostly followed the Avrami-Erofeev kinetics model.read more

Modification of the integral isoconversional method to account for variation in the activation energy
TL;DR: Vyazovkin et al. as discussed by the authors used an integration technique that properly accounts for the variation in the activation energy, which was implemented as a modification of the earlier proposed advanced isoconversional method and applied to the thermal decomposition of calcium oxalate monohydrate and ammonium nitrate.

TL;DR: Rational approximations have been derived for the integral of the Arrhenius function dT which is important in the kinetic analysis of thermogravimetric data and is found to be equivalent to the Gorbachev approximation.

Kinetic analyses using simultaneous TG/DSC measurements: Part I: decomposition of calcium carbonate in argon
TL;DR: In this paper, the authors performed dynamic kinetic analyses on CaCO3 using simultaneous thermogravimetry and differential scanning calorimetry (DSC) measurements in both wet and dry flowing Ar. Although the quality of the DSC results was inferior compared with those based on TG, it is clear that they yield different results in subsequent kinetic analyses using a wide range of numerical methods.
