摘要：

The crystallization kinetics of Sb9.1Te20.1Se70.8 chalcogenide glass have been studied by differential scanning calorimetry (DSC). The effective activation energy of crystallization has been evaluated on the basis of the Kissinger equation and the method of Matusita et al. The Sestak-Berggren model has been used for the description of DSC crystallization data as it provides the best fit to the experimental results. It has been found that the Johnson-Mehl-Avrami model could be applied at very high rates of heating. (c) 2005 Elsevier B.V. All rights reserved.
