Abstract

The kinetic treatment of glass formation has been extended to describe crystallization on reheating a glass and to estimate critical cooling rates for glass formation from three measurable quantities, Tg, TL and the heat of fusion. The crystallization temperature on reheating a glass is found to depend strongly on the heating rate and on the barrier to crystal nucleation, and only weakly on the cooling rate used to form the glass. The analysis indicates that simple DTA analyses can be used to estimate the magnitudes of the nucleation barriers of various materials. The simplified treatment of glass formation gives predictions which agree within about an order of magnitude with those obtained using the full detailed kinetic analysis.
