Abstract
Results of Differential Scanning Calorimeter (DSC) under non
isothermal condition on Se98 In2-χ Snχ (χ=0.0.5,1,1.5)
chalcogenide glasses have been reported and discussed. ln the glassy
region, the dependence of the glass transition temperature Tg on the
heating rate or obey a power law, Tg=To{ɑ}ʏ ,and the glass transition
activation energy decreases with the addition of Sn. The crystal
growth kinetics has been investigated using Kissinger, Gao et.al, and
Ozawa equations. Results indicate that the crystallization activation
energy decreases and the crystallization ability is retarded, due to the
formation of cross-linked structure, with the addition of Sn. Besides to
that the crystal growth is found to occur in 2-dimensions.
Investigation of thermal stability through the calculations of the
temperature difference TC-Tg, S-parameter, Hruby number,
crystallization rate factor and the enthalpy released during the
crystallization process, indicates that Se98 In0.5 Sn1.5 glass is thermally
most stable in the composition range of study
