Abstract :Differential scanning calorimetry insert ignore into journalissuearticles values(DSC); is performed at different heating rates under non-isothermal conditions to calculate the activation energy of crystallization Ec for chalcogenide glasses Se0.68Ge0.22M0.10 insert ignore into journalissuearticles values(M = Cd, In and Pb); using the well known Kissinger`s relation, Matusita-Sakka theory and the method of Augis-Bennett. The overall mean bond energy of these glassy alloys has been evaluated using theory of Tichy and Ticha. A good correlation has been found between Ec and . This indicates that the overall mean bond energy plays an important role in the thermal crystallization of chalcogenide glasses.
