This paper presents the result of thermodynamic studies on (Se80Te20)100-xAgx ( 1< x < 4) glasses under non isothermal conditions using differential scanning calorimetric technique. The crystallization kinetics has also been discussed. Thermodynamic parameters like entropy difference between glassy and the crystalline phase, difference of Gibbs free energy, specific heat, and the enthalpy released during phase transformation have been evaluated. The heat capacity jump and fragility of these alloys are also calculated. The results show that the stability of sample is minimum for (Se80Te20)99Ag1 and maximum for (Se80Te20)97Ag3 among all the samples.
