| Description
| - The structure-viscosity relationship of 15Na(2)O center dot xMgO center dot(10-x)CaO center dot 75SiO(2) (x = 0, 2, 4, 6, 8, 10) glasses was studied. The structure of studied glasses was described by the thermodynamic model of Shakhmatkin and Vedishcheva. Thermodynamic modeling resulted in eight components with significant abundance in the studied glasses, i.e. SiO2, 2MgO center dot SiO2, MgO center dot SiO2, Na2O center dot 3CaO center dot 6SiO(2), Na2O center dot CaO center dot 5SiO(2), Na2O center dot MgO center dot 4SiO(2), Na2O center dot SiO2 and Na2O center dot 2SiO(2). Due to significant positive correlations between equilibrium molar amounts of (2Mg0 center dot SiO2MgO center dot SiO2), (Na2O center dot 3CaO center dot 6SiO(2)-Na2O center dot CaO center dot 5SiO(2)), (Na2O center dot MgO center dot 4SiO(2)-Na2O center dot SiO2), and (Na2O center dot SiO2Na2O-2SiO(2)) only four significant components were considered in the regression treatment, namely SiO2, MgO center dot SiO2, Na2O center dot 3CaO center dot 6SiO(2), and Na2O center dot 2SiO(2). The experimental viscosity data obtained in the viscosity range from 10(2) dPa.s to 10(12) dPa.s were alternatively described by various commonly used viscosity equations Adam and Gibbs, Avramov and Milchev, and MYEGA. The compositional dependence of parameters of the above viscosity equations was described by multi-linear formulas taking as independent variables the equilibrium molar amounts of significant components of the thermodynamic model. The statistical analysis of the non-linear regression results was performed and only the statistically significant members were retained in the multi-linear forms.
