abstract = {The viscosity model recently developed for fully liquid
pure oxides and binary systems is extended to describe the
viscosity of multicomponent systems, based on the
thermodynamic modified associate species model. In the model
the viscosity is linked to the distribution of associate
species as well as the connectivity of associate species. To
describe the viscosity for multicomponent systems, the
ternary associate species are introduced. The focus of the
present paper is to describe the viscosity of the system
SiO2–Al2O3–CaO–MgO–Na2O–K2O and its ternary or
higher order subsystems. The model shows a good performance
in describing the viscosity using only one set of model
parameters, which all have a clear physico-chemical meaning.
The viscosity behavior when substituting one network
modifier for another at constant SiO2 contents is well
described. The Al2O3-induced viscosity maximum is also well
described, in which the position and magnitude of the
viscosity maximum as a function of composition and
temperature (charge compensation effect) are properly
predicted. Another viscosity maximum when replacing Al2O3
with SiO2 for constant contents of the network modifiers is
well presented. Moreover, the current model is
self-consistent, in which the extension of viscosities from
lower order systems to higher order systems works well, and
vice versa.},
