Viscosity and activation energy for viscous flow of PbO-WO3-P2O5 glasses
Original language description
The temperature dependence of viscosity of three compositional series of PbO-WO3-P2O5 glasses with compositions (0.5-x/2) PbO center dot xWO(3)center dot(0.5-x/2)P2O5, x=0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6; 0.5PbO center dot xWO(3)center dot(0.5-x)P2O5, x=0.1, 0.2, 0.3; and (0.5-x)PbO. xWO(3)center dot 0.5P(2)O(5), x=0.1, 0.2, 0.3, 04 measured by thermomechanical analysis is reported. The Andrade viscosity equation was successfully used to describe the temperature dependence of viscosity and to evaluate ofthe temperature independent activation energy for viscous flow. The results are discussed in terms of the glass structure by considering the network forming/modifying function of individual oxides. A simplified structural model is proposed and verified by a multilinear regression analysis of the compositional dependence of the activation energy for viscous flow and the glass transition temperature.
