Abstract

The present paper reports on the differential scanning calorimetric (DSC) behaviour of glassy Se80Te20 containing Ag up to 10 at%. DSC runs were taken at different heating rates. Well-defined endothermic and exothermic peaks were obtained at glass transition and crystallization temperatures. The glass transition temperature (Tg) and crystallization temperature (Tc) increase with the increase in heating rate. Tg and Tc both decrease with increase in Ag concentration. The activation energies for glass transition and crystallization also decrease with Ag incorporation in the Se80Te20 binary alloy. Copyright © 2000 John Wiley & Sons, Ltd.
