Název v původním jazyce

Thermodynamic model and viscosity of Ge-S glasses

Popis výsledku v původním jazyce

The structure-viscosity relationship of GexS(1-x) (x = 0.30, 0.32, 0.33, 0.333, 0.34, 0.36, 0.38, 0.40, 0.42, and 0.44) glass melts was studied. The structure of studied glass melts was described by the thermodynamic model of Shakhmatkin and Vedishcheva.Thermodynamic modeling resulted in four components with significant abundance in the studied glasses, i.e., Ge, S, GeS, and GeS2. The results of thermodynamic model allowed interpretation of compositional dependence of T (g) in form of linear function of equilibrium molar amounts of system components. The experimental viscosity data were alternatively described by various commonly used viscosity equations-Adam and Gibbs, Avramov and Milchev, and MYEGA. The compositional dependence of parameters of theabove viscosity equations was described by multilinear formulas with independent variables alternatively defined as the total molar fractions of Ge and S in glass, and the equilibrium molar amounts of components of the thermodynamic model
