Temperature Dependence of the Viscosity of Chalcogenide Glass-Forming Melts

  • A. S. Tverjanovich


A procedure is proposed for extrapolating (up to the boiling point) the temperature dependences of the viscosity of chalcogenide glass-forming melts, which are measured in the softening temperature range. It is shown that the calculated and experimental data obtained for a series of stoichiometric glass-forming melts are in satisfactory agreement. The viscosity is calculated for the GeS2 melt, for which experimental data on viscosities of less than ∼1016 P are not available in the literature.
