Abstract
At different heating rates, the crystallization temperature (Tc) are obtained from the non-isothermal differential scanning calorimetry (DSC) measurements of bulk Se82–xTe18Sbx (x = 0, 4, 8 and 12) chalcogenide glasses prepared by melt quench technique. It was observed that the crystallization temperatures increase with increasing heating rates and also by increasing Sb concentration in Se–Te system. The activation energy of crystallization (Ec), the Avrami exponent (n) and rate of crystallization (Kp) have been determined from the different models. Glassy nature of as prepared samples has been confirmed using DSC techniques.
