Abstract

In quantitative studies of the structural stability of Te-Cl and Te-Br glasses, specific attention has been devoted to determining the kinetics of their overall crystallization process and the glass composition range in which chemical decomposition occurs at elevated temperatures. The calorimetric studies reveal that the tendency of crystallization or thermal decomposition of these glasses is related to phase-diagram characteristics. It seems that the structure of these glasses is not an idealized random arrangement as described by the classic model. Underlaying causes for this deviation from a perfect random arrangement to one involving a degree of ordering ( structural group ) is discussed.
