Results of differential scanning calorimetry under isothermal and non-isothermal conditions on Bi10Se80In10 glass are reported and discussed. By using the Johnson-Mehl-Avrami equation the activation energies for crystal growth have been evaluated and the crystallization mechanism has been studied. The results indicate that the crystallization process is a two-dimensional growth. The average calculated value of activation energy is 330.2 kJ mol-1 for Bi10Se80In10 chalcogenide.
