Abstract

Crystallization processes of GexS1-x (0.322≤x≤0.44) glasses have been studied by thermal analysis and a new simple method of kinetic analysis is proposed. This method allows the definition of an appropriate model characterizing the crystallization process of glass, as well as calculation of reliable kinetic parameters. Results of kinetic analysis allow definition of a thermal stability criterion which has a general applicability for any glass-forming system.

Key words

Zusammenfassung

Mittels Thermoanalyse wurden die Kristallisationsprozesse von GexS1-x (0.322≤x≤0.44) untersucht eine neue einfache Methode für die kinetische analyse vorgeschlagen. Diese Methode gestattet die Definition eines entsprechenden Modelles zur Beschreibung des Kristallisationsprozesses als auch die Berechnung zuverlässiger kinetischer Parameter. Die Ergebnisse der kinetischen Analyse ermöglichen die Festlegung eines thermischen Stabilitätskriteriums, was bei allen glasbildenden Systemen Anwendung finden kann.
