Notes:
High temperature viscosity and density of glass melts, glass transition temperature, andthermal expansion coefficient of glasses from the system MgO-CaO-B2O3-Al2O3-SiO2 withcomposition close to the E-glass were measured and interpreted with respect to the effect of CaOand MgO content on their physical properties. The Andrade model was applied for description ofthe temperature dependence of the glass viscosity within studied temperature range. The regressionformaulae describing the compositional dependence of the viscosity points T2 = T( η = 100 dPa.s),T3 = T( η = 1000 dPa.s), the glass transition temperature, Tg, thermal expansion coefficient of glass,αg, and of the viscous flow activation energy, Ea, were proposed
