Thermal Behaviour and Non Isothermal Kinetics of Se60 S40-x Tex

Abstract

Differential scanning calorimetry (DSC) of two amorphous alloys of the ternary
isoelectronic system Se60 S40-x Tex (x = 15 and 25) at different heating rates are
reported and discussed. Characteristic temperatures, glass transition
temperature (Tg), crystallization temperature (Tc) and melting temperature (Tm)
and the glass forming tendency (Kgl), have been estimated. The kinetic
parameter (Ec) has been determined using non- isothermal multi-scan technique
of Kissinger approach. The calculated order of reaction (n) indicate that bulk
crystallization with one-dimensional growth occurs for these glasses. Cyclic
scanning technique has been used to demonstrate the structural change during
two consecutive heating-cooling cycles.
