The glass transition and the crystallization kinetics of Zn10Se90 glass by differential thermal analys is (DTA) technique under non-isothermal conduction were studied. The effective activation energies of the glass transition and the crystallization have been
evaluated on the basses of the Kissinger and Matusita et al. approximations. Kineticparameters of the crystallization process are significantly influenced by the heating rate. We have compared the experimental DTA with the calculated data curves for
Zn10Se90 system using the Johanson-Mehl-Avrami (JMA) and Sestak-Berggren SB(M,N) models. Simulation results indicated that, the SB(M,N) model is more
suitable for describing the crystallization kinetics for the studied composition. Furthermore, the crystalline phases of annealed Zn10Se90 were characterized by X-ray diffraction. The surface morphology of the annealed samples was examined using scanning electron microscopy (SEM).
