Abstract
An applied kinetic model has been developed for processing DSC peaks of transitions between states, determining the temperature–time dependence of the degree of transition and combining the fundamental theory of Kolmogorov–Johnson–Mehl crystallization, simplified for practice, with the semi-empirical Erofeev model. In the development of this applied model, the concept of a “thermodynamic factor” is introduced, which allows a transition in the kinetics of phase transformations of condensed matter. The application of the new approach is demonstrated by the example of studying the dependences of temperature and enthalpy of fusion on the average atomic mass of stable germanium isotopes, data on which, as new chemical individuals, are of a fundamental nature and can serve as reference information.
