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 Se78Te20Sn2 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 (Tg), Lasocka's glass transition parameters (i.e., A1 and B1), and the glass transition activation energy (Eg) have been calculated. Similarly, we have determined the crystallization temperatures (on-set value To, and peak value Tc) and melting temperature (Peak value Tm), Lasocka's crystallization parameters (i.e., A2 and B2), crystallization rate constant K, and the corresponding activation energy (Ec). Knowing the values of kinetic temperatures of glass transition/ crystallization, the thermal stability, and the glass-forming tendency of ternary Se78Te20Sn2 and quaternary Se76Te20Sn2M2 (M = Ag, Bi, Cd, and Zn) alloys have been also determined.
