Study Of Glass Transition Kinetics In Glassy Se90bi10-Xagx (X = 0, 2, 4,6) Alloys

Under non-isothermal conditions, differential scanning calorimetric scans have been taken for glassy Se90Bi10-xAgx (x = 0, 2, 4, 6 at.%) alloys at four heating rates (5, 10, 15, 20 K/min) for the thermal analysis of glass transition kinematics. Single endothermic and exothermic peaks are observed for glass transition and crystallization phenomenon respectively in aforesaid glasses. Activation energy for the glass transition process (E-g) has been calculated using Moynihan and Kissinger model. The dependence of glass transition temperature on the heating rate beta has been reported. The value of (T-c - T-g) and stability parameter S have been calculated for each glassy alloy.
