Abstract: Thermal crystallization study of Te15(Se100-xSbx)85 glassy alloys ( x= 0, 1, 2, 3 and 4 at. %) has been reported in this communication. Differential thermal analysis (DTA) has been used to carry out the study. DTA has been performed at different heating rates of 10, 15, 20 and 25 K/min. DTA spectra have been analysed for crystallization temperature (Tc) and onset temperature of crystallization (To). The crystallization temperature and onset temperature of crystallization have been found to shift to higher value with increase in heating rate (β) and with increase in Sb content (x). The activation energy of crystallization (Ec) has been calculated using the modified Kissinger, Matusita-Sakka, Augis-Bennett and Ozawa’s approaches. The activation energy of crystallization has been found to increase with Sb content, implying more crystallization. Ec values calculated using different methods are in good agreement with each other.
