Viscosity of Se-Te glass-forming system

Abstract

This work is focused on viscosity of chalcogenide system Se-Te. Viscosity values of four glass-forming compositions in this system (containing 5, 10, 20 and 30 at.% of tellurium) were measured by penetration and parallel-plate method in the region of undercooled melt and glass. These results are combined with literature data for melt region. The kinetic fragility and viscosity glass transition temperature values obtained by different methods are calculated from measured data.
