摘要：
Differential scanning calorimetry (DSC) is performed at different heating rates under non-isothermal wconditions to calculate the activation energy of crystallization Ec for chalcogenide glasses Se0.68Ge0.22M0.10 (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 < E > of these glassy alloys has been evaluated using theory of Tichy and Ticha. A good correlation has been found between Ec and < E >. This indicates that the overall mean bond energy plays an important role in the thermal crystallization of chalcogenide glasses.
