Abstract
•The crystallization kinetics of Se90Te10 and (Se90Te10)95S5 were analyzed.•These bulk samples were analyzed with different heating rates.•Analysis and experimental data revealed Eg and EC are different with additives.•Thus, the Sestak–Berggren model was used for characterizing DSC crystallization.•The Johnson–Mehl–Avrami model can be applied at very high heating rates.
Initially, Sulfur (S) doping in Se90Te10 glassy alloy was utilized for clarifying the effects produced by minerals on its glass mesh and kinetic characteristics. The crystallization kinetics of bulk Se90Te10 and (Se90Te10)95S5 with different heating rates were analyzed by the differential scanning calorimetry. The processes of the alloy recrystallization after the thermal treatment were recognized by X-ray diffraction. The activation of energy, Eg, of glass transition crystallization, Ec, was utilized for determining various kinetic models. The analysis and experimental data revealed that Eg and EC differ for the additive elements. The effective Ec of crystallization was calculated based on the Kissinger formula. Thus, the Sestak–Berggren model was used for characterizing the DSC crystallization information when it agreed to the experimental results. Consequently, it was found that the Johnson–Mehl–Avrami model can be applied at high heating rates.
