Abstract
Non-isothermal Differential Scanning Calorimetric (DSC) studies were done on Se100-XM(M=In, Sb)X chalcogenide glasses prepared by the melt quenching technique. The composition-dependent activation energy for glass to crystal transformation (ΔEc) and the pre-exponential factor (Ko) of the Arrhenius expression were obtained on the basis of the Augis and Bennett's method. A linear dependence between ΔEc and lnK0 was observed in both systems implying the existence of compensation effects of the Meyer-Neldel type. These compensation effects confirmed the applicability of Meyer-Neldel Rule (MNR) for the non-isothermal crystallization in the present systems.
