Crystallization processes of Se80Te20-xCdx (x = 0, 4, 8, 10
and 12) alloys at different heating rates have been studied by differential
scanning calorimeter (DSC) by using non-isothermal technique. The values of
glass transition temperature (Tg) and crystallization temperature
(Tc) are found to be composition and heating rate dependence. From the
heating rate dependence of glass transition temperature and crystallization
temperature, the activation energy of crystallization (ΔEc),
the activation energy for structural relaxation (ΔEt) and the
order parameter (n) have been calculated. It was observed that Se80Te16 Cd4
has a minimum value of activation energy of structural
relaxation (ΔEt), which indicates that this particular glass
has a larger probability to jump to a state of lower configurational energy
and higher stability in the glassy region.
