Thermal analysis for study of influence of Cd, In, and Sb on glass transition kinetics in glassy Se_(80)Te_(20) alloy using DSC technique

摘要

In this paper, we have incorporated Cd, In, and Sb in glassy Se_(80)Te_(20) alloy to see the metal-induced effect of these additives on its glass network and kinetic properties. Specifically, we report results of systematic calorimetric measurements to study the glass transition kinetics. The glass transition behavior of glassy Se_(80)Te_(20) and glassy Se_(80)Te_(10)M_(10) (M = Cd, In, Sb) alloys has been analyzed by differential scanning calorimetric technique at various heating rates. The activation energy (E_g) of glass transition was determined using different kinetic models. Analysis of experimental data reveals that Eg varies with the additive elements. The value of various kinetic parameters such as thermal stability, Hruby number, and fragility index has been calculated in non-isothermal mode.
