Effect of Ag addition on glass transition and crystallization in Se80Te20 glass

The present paper reports on the differential scanning calorimetric (DSC) b ehaviour 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 gla ss transition temperature (T-g) and crystallization temperature (T-c) incre ase with the increase in heating rate, T-g and T-c both decrease with incre ase in Ag concentration, The activation energies for glass transition and c rystallization also decrease with Ag incorporation in the Se80Te20 binary a lloy.
