Study of crystallization rate constant of (Se80Te20)100-xAgx chalcogenide glasses
Published online by Cambridge University Press: 08 October 2010
Abstract
The present paper reports the preparation of (Se80Te20)100-xAgx (0 ≤ x ≤ 4) chalcogenide glasses in bulk by using melt quenching technique. DSC runs of these samples have been taken at four different heating rates (5, 10, 15, 20 K/min). The variation in crystallization temperature Tc with Ag concentration at different heating rates has been studied. A strong co-relation between the pre-exponential factor K0 of rate constant K of crystallization and activation energy of crystallization Ec has been observed. The variation of rate constant K with composition and the dependence of Ec with Ag concentration have been studied.
