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 (Delta E-c) and the pre-exponential factor (K-0) of the Arrhenius expression were obtained on the basis of the Augis and Bennett's method. A linear dependence between Delta E-c, and lnK(0) 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. (C) 2014 Elsevier Ltd and Techna Group S.r.l.
