摘要

AbstractOriginal viscosity data for Ge0.5Se99.5and Ge2Se98chalcogenide glass-formers were measured by thermomechanical analyzer in the region from 105to 1013Pa·s. The combination of two experimental methods, penetration one and parallel-plate one, was used. Experimental details, important remarks and our experience with these methods are discussed and summarized. Experimental data for studied chalcogenides are correlated with previously measured data in Ge-Se system and also combined with previously published data for melt region. The Vogel-Fulcher-Tammann equations are used for fitting experimental and literature data and their parameters are discussed.Highlights?Experience of authors with penetration and parallel-plate viscometry is summarized.?Viscosity of Ge0.05Se99.5and Ge2Se98undercooled melts and glasses are tabulated.
