Impact of Ag, Bi, Cd, and Zn incorporation on the kinetic parameters of glass transition/crystallization in chalcogens Se- and Te-rich ternary glass

The present study examines the impact of a few additives, i.e., silver (Ag), bismuth (Bi), cadmium (Cd), and zinc (Zn) on the kinetics of glass transition and crystallization in glassy Se 78 Te 20 Sn 2 alloy. This is accomplished by performing the calorimetric experiment in non-isothermal mode. To perceive the metal-induced consequences of Ag, Bi, Cd, and Zn as foreign atoms on the kinematics of glass transition, the glass transition temperature ( T g ), Lasocka’s glass transition parameters (i.e., A 1 and B 1 ), and the glass transition activation energy ( E g ) have been calculated. Similarly, we have determined the crystallization temperatures (on-set value T o , and peak value T c ) and melting temperature (Peak value T m ), Lasocka’s crystallization parameters (i.e., A 2 and B 2 ), crystallization rate constant K , and the corresponding activation energy ( E c ). Knowing the values of kinetic temperatures of glass transition/ crystallization, the thermal stability, and the glass-forming tendency of ternary Se 78 Te 20 Sn 2 and quaternary Se 76 Te 20 Sn 2 M 2 ( M = Ag, Bi, Cd, and Zn) alloys have been also determined.
