The present work reports the effect of some additives (Ag, Cd, and Zn) on the crystallization kinetics of glassy Se70Te30 alloy in terms of kinetic parameters of crystallization. Differential scanning calorimetry (DSC) technique is used for this purpose in non-isothermal mode. Various kinetic parameters (crystallization temperature T-c, activation energy of crystallization E-c, rate constant K, and order parameter n) are calculated using the non-isothermal methods.
