Study of Crystallization Process in Se 80 In 10 Pb 10 by Iso-Conversional Methods

Abstract

The crystallization kinetics of Se80In10Pb10 chalcogenide glass is studied using differential scanning calorimeter (DSC) at different heating rates (5, 10, 15 and 20 K/min) under non-isothermal conditions. Four iso-conversional methods (Kissinger-Akahira-Sunose, Flynn-Wall-Ozawa, Tang and Straink) were used to determine various kinetic parameters: crystallization temperature (Tα), activation energy of crystallization (Eα), Avrami exponent (nα) in non-isothermal mode. The transformation from amorphous to crystalline phase in Se80In10Pb10 is considered as a single step reaction mechanism.
