ABSTRACT
In the article, the glass transition processes of the Sb80Se20 chalcogenide composition were studied by the differential scanning calorimetry (DSC)
method depending on the heating rate in the temperature range of t=20÷300°C. It was determined that as a result of the increase in the heating rate (q) (in the range
of q=2.5-17.5 °C/min), the "fragility" coefficient (m) undergoes a slight decrease, which leads to a partial increase of thermal stability (∆T) and a weak increase of
glass-forming ability [or Hruby number (Hr)], thermal stability parameters (Hʹ, S).
Keywords: chalcogen, glass, amorphous, fragility coefficient.
