Description

Analysis of known experimental data on viscosity of B2O3 and binary AxO4-B2O3 systems in the area of 1013-101 P is given. General regularities of the Viscosity change due to composition and temperatures are established. The regularities interpretation is presented on the basis of the theory of absolute velocities of processes. The parameters of the latter make it possible to give unambiguous characteristics of changes in strength (cohesion) of glass spatial skeleton, the volume of kinetic units and the length of glass melts (the rate of their fragility). The quantitative ratios between viscous characteristics and structure are found with application of the NMR-results, elastic modules of glasses and melts and spectroscopic data
