Calorimetric studies have been made in glassy Se80−x Te20Sbx where 0 ≤x ≤ 15 with a view to calculate the crystallization kinetic parameters. Multi scantechnique has been used to calculate the activation energy of crystallizationΔE and the order parameter (n). The results indicate that ΔE ishighly composition dependent in these glasses. A discontinuity in ΔE is observedat 10% of Sb which is explained in terms of mechanically optimised structure at aparticular average co-ordination number.
