    Viscosity of (GeSe2)x(Sb2Se3)1-x Undercooled Melts

  • Original language description

    Viscosity of (GeSe2)x(Sb2Se3)1-x undercooled melts (x = 0.4-0.8) was measured using parallel-plate method and penetration method. By using these two techniques viscosity of the whole measurable region of undercooled melt and of the part of glass region can be measured. In this relatively broad viscosity interval (seven orders of magnitude) all measured samples show Newtonian behavior and the dependence of their viscosity on temperature can be described by a simple Arrhenius equation. The kinetic fragilities calculated from these dependencies show similar compositional dependence as heat capacity changes at glass transition measured by DSC.

    Viskozity podchlazených tavenin systému (GeSe2)x(Sb2Se3)1-x

  • Czech description

    Viskozity podchlazených tavenin systému (GeSe2)x(Sb2Se3)1-x (x = 0.4-0.8) byly změřeny pomocí penetrační metody a metody transversálního toku. V celé oblasti měřených viskozit vykazují všechny vzorky Newtonovské chování a jejich viskozitní závislosti lzepopsat pomocí jednoduché rovnice Arrheniova typu. Kinetické fragility určené z těchto závislostí vykazují stejnou kompoziční závislost jako změny tepelných kapacit v oblasti skleného přechodu určené pomocí DSC.
