Summary

The present paper reports the Differential Scanning Calorimetric (DSC) study of some Ag doped Se-Te chalcogenide glasses. DSC runs were taken at different heating rates. Well-defined endothermic and exothermic peaks were obtained at glass transition and crystallization temperatures. The variation of glass transition temperature T gwith Ag concentration has been studied. It has been found that T gdecreases with increase in Ag concentration. The heating rate dependence of T gis used to evaluate the activation energy of glass transition (DE t). The value of<span style='font-size:10.0pt; font-family:"SymbolProp BT";mso-bidi-font-family:"SymbolProp BT"'>DE thas been found to increase with increase in Ag concentration followed by nearly constant value at higher concentrations of Ag.
