摘要

Results of differential thermal analyses (DTA) under non-isothermal conditions on three glasses of the Se85-xTe15Sbx(x = 0, 3 and 9) are reported and discussed. The glass transition temperatures (T-g), the onset crystallization temperatures (T-c), and the peak temperature of crystallization (T-p) were found to be dependent on the compositions and the heating rates. From the dependence on heating rates of (T-g) and (T-p) the activation energy for glass transition (E-g) and the activation energy for crystallization (E-c) are calculated and their composition dependence discussed. The crystalline phases resulting from DTA have been identified using X-ray diffraction and scanning electron microscopy (SEM). The results indicate one dimensional growth for the compositions Se82Te15Sb3 and Se76Te15Sb9 and two dimensional growth for the composition Se85Te15. The kinetic parameters determined have made it possible to discuss the glass-forming ability. (C) 1998 Elsevier Science B.V. All rights reserved. [References: 24]
