Abstract
Results of thermal analysis performed at different heating rates on the composition Bi5Ge20Se75 are reported and discussed. The values of crystallization temperature (T c) and the peak temperature of the crystallization (T p) were found to be dependent on the heating rates. The activation energy of crystallization E c was evaluated by five different methods. The average value of E c is equal to 119.64+ 6.97 kJ mol−1.
The crystallization data are examined in terms of recent analysis developed for non-isothermal conditions. The results indicate a two-dimensional crystal growth for the investigated composition.
