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 (T_α), activation energy of crystallization (E_α), Avrami exponent (n_α) in non-isothermal mode. The transformation from amorphous to crystalline phase in Se₈₀In₁₀Pb₁₀ is considered as a single step reaction mechanism.
