Crystallization kinetics of amorphous Se Part 1. Interpretation of kinetic functions

Popis výsledku v původním jazyce

Differential scanning calorimetry was used to study crystallization behavior in selenium glass under non-isothermal conditions. The crystallization kinetics were described in terms of the Johnson-Mehl-Avrami nucleation-growth model; activation energies and kinetic parameter m (JMA) were determined. The study was performed in dependence with particle size, so that a novel approach to the evaluation of crystallization kinetics-the advanced interpretation of characteristic kinetic functions-could be employed. Extensive discussion of all aspects of a full-scale kinetic study for a complex crystallization process was performed within the framework of the introduced conception. The complexity of the crystallization process was found to be represented by veryclosely overlapping consecutive competing surface and bulk nucleation-growth mechanisms. Mutual interactions of both mechanisms as well as all other observed effects were explained in terms of thermal gradients, surface crystallization c
