Evaluation of glass-stability criteria for chalcogenide glasses: Effect of experimental conditions

Popis výsledku v původním jazyce

The Hruby, Weinberg and Lu-Liu glass-stability criteria for chalcogenide materials were for the first time demonstrated to be significantly dependent on the experimental conditions (heating rate and sample form). Origins of the heating rate and sample form dependencies were found to subsist in the magnitude of activation energies of involved thermokinetic phenomena and amount of stress/mechanically induced defects acting as crystallization centers, respectively. As-prepared bulk samples were found to bemost convenient for determination of glass stability, both from reproducibility and simplicity points of view. Good empirical correlation of the glass stability and glass-forming ability was found for the three criteria and nine tested chalcogenide materials. A novel performance index evaluating invariability of the glass-stability criteria with respect to experimental conditions was introduced. It was found that the Hruby criterion exhibited the lowest normalized variability due to the
