Phase Transformation and Kinetics of Crystallization of Ge0.5Sn0.5Se2.5 Glass

In the present work, Differential Scanning Calorimetry (DSC) has been performed at different heating rates under non‐isothermal conditions to study the crystallizalion kinetics of the Ge0.5Sn0.5Se2.5 chalcogenide glass. Four different methods of analysis (Kissinger equation, Ozawa equation, Matusita equation and Augis and Bennett method) of the non‐isothermal DSC data and various kinetic parameters i.e the activation energy of glass transition (Et), the activation energy of crystallization (Ec), order parameter, rate constant, frequency factor have been determined. The rate constant K (indicator of the rate of to crystalline phase transformation) has been evaluated using the method of Augis and Bannett. Further, the rate of crystallization and dimensionality of growth has also been investigated for the above system.
