TL;DR: The most debatable and discrepant viewpoints of non-isothermal kinetics are discussed in the form of twelve questions and answers as discussed by the authors, including the reputation of nonisothermal analysis when carried out by thermoanalysts, the consequences of simplified concepts transferred from the kinetics of homogeneous reactions, the physical meaning of basic kinetic parameters in solid-state processes, the kinetic compensative effect and interdependence of kinetic parameters using the Arrhenius rate constant, the mutual usefulness of differential and integral methods of kinetic data evaluation, their accuracy and correctness, the reliability of
Abstract: The most debatable and discrepant viewpoints of non-isothermal kinetics are discussed in the form of twelve questions and answers. The reputation of non-isothermal kinetics when carried out by thermoanalysts; the consequences of simplified concepts transferred from the kinetics of homogeneous reactions; the physical meaning of basic kinetic parameters in solid-state processes; the kinetic compensative effect and interdependence of kinetic parameters using the Arrhenius rate constant; the mutual usefulness of differential and integral methods of kinetic data evaluation; their accuracy and correctness; the reliability of DTA measurements; non-isothermal versus isothermal investigations; equilibrium and kinetic data and their mutual effect; the extended discussion initiated by MacCallum and Tanner; non-isothermal data publication policy; and finally the use of computers.

TL;DR: In this article, various manifestations of the kinetic compensation effect are considered in reactions involving the participation of solid substances under isothermal and nonisothermal conditions, as well as manifestations of other isoparametric correlations.
Abstract: Various manifestations of the kinetic compensation effect are considered in reactions involving the participation of solid substances under isothermal and nonisothermal conditions, as well as manifestations of other isoparametric correlations. It is shown that isoparametric correlations can be used for the analysis of solid-phase reactions and the exclusion of artefacts in nonisothermal kinetics.

TL;DR: Theoretical results for nucleation and growth controlled transformations indicate that a non-isothermal generalization is only possible along the lines of the isokinetic hypothesis, i.e., the invariance of the rate equation under any thermal conditions.

TL;DR: In this article, the effects of self cooling on the apparent kinetics of the nonisothermal dehydration of crushed crystals of lithium sulfate monohydrate were investigated using TG accompanied by DTA and power-compensation type DSC.
Abstract: The effects of self cooling on the apparent kinetics of the nonisothermal dehydration of crushed crystals of lithium sulfate monohydrate were investigated using TG accompanied by DTA and power-compensation type DSC. Linearity of the sample heating rate on the TG-DSC system is much better than that on the TG-DTA. Kinetic obedience and Arrhenius parameters obtained from the TG-DTA deviate considerably from those obtained from the TG-DSC; the latter are the more accurate due to the better linearity of the sample heating rate.
