Abstract

The compositional dependence of the glass transition temperature (Tg), and the temperature of the maximum rate of crystallization (Tp) of As-Se glasses containing Sb has been measured using non-isothermal DSC. The variation of these characteristic temperatures is found useful in interpreting the structural changes in As-Sb-Se glasses. The role of Sb in these glasses and its effect on the crystallization characteristics is analyzed.

Zusammenfassung

Die AbhÄngigkeit der Glasumwandlungstemperatur (Tg) und der Temperatur bei maximaler Kristallisationsgeschwindigkeit (Tp) von der Zusammensetzung von Sb enthaltenden As-Se-GlÄsern wurde mittels nicht-isothermer DSC bestimmt. VerÄnderungen dieser charakteristischen Temperaturen haben sich als nützlich zur Interpretation der strukturellen VerÄnderungen in As-Sb-Se-GlÄsern erwiesen. Die Rolle des Sb in diesen GlÄsern und dessen Wirkung auf die Kristallisationskenndaten wird untersucht.
