About the remarks on the application of the combined Kolmogorov-Erofeev-Kazeev-Avrami-Mampel equation in the kinetics of non-isothermal transformations

Short Communication


An analysis is made of the method proposed by Gorbachev for the kinetic study of non-isothermal transformations using the KEKAM equationα=1−exp(−ktn). It is demonstrated that the procedure cannot be used to determine either the kinetic exponentn or the activation energyE.
