Abstract
A method of approximate prediction of the viscosity of multicomponent silicate melts was proposed in view of practical use, on the basis of the relationship between the network parameter deduced from the viscosity of melts and the anion-cation attraction parameter. It was postulated in the method that the anion-cation attraction parameter is considered to be melt-structure (or polymerization)-dependent. The generalized relationship exists between the network parameter and the modified anion-cation attraction parameter.
In order to check the validity of the above estimation method, viscosity data for multicomponent silicate melts have been collated. Theoretical values based on the method show excellent agreement with the experimental data.
