Abstract The use of the different equations proposed to study the kinetics of the glass-to-crystal transition from DTA curves has been extended to include the evaluation of the kinetic parameters of polymorphic transitionS. The transformation kinetics of CaCO3 (aragonite to calcite) and PbO (litharge to massicot) are the examples studied. The kinetic results of both transformations, obtained by the analysis of DTA curves, differ widely from those revealed by the analysis of the isothermal kinetic data. This discrepancy is probably due to erroneous simplifications used in deriving the equations applied in non-isothermal conditions.
