Calorimetrie studies of Se_(75)Te_(15)Cd_(10) and Se_(75)Te_(10)Cd_(10)ln_5 multicomponent chalcogenide glasses

摘要

The crystallization kinetics of Se_(75)Te_(10)Cd _(10)In_5 multi-component chalcogenide glass was investigated using differential scanning calorimetry (DSC) at different heating rates of S, 10, IS and 20 K/min. The average activation energy of crystallization and the activation energy of glass transition were found to be 102.3 and 124.2 kJ/mol, respectively. The Se_(75)Te_(10)Cd_(10)In_5 multi-component chalcogenide glass is more stable than Se_(75)Te _(15)Cd_(10) ternary glass. The non-integer value of the Avrami index (n=2.02) indicates that volume nucleation and one-dimensional growth are occurring in amorphous-crystalline transformations.
