摘要：
A model of chemical interaction between oxides of aluminum and alkaline-earth metals is proposed. The model provides the basis for an algorithm that makes it possible to calculate the viscosity of melts in the MgO-CaO-SrO-BaO-Al2O3-SiO2 system at an arbitrary content and any combination of components in the viscosity range from 10(-1) to 10(6) P. The algorithm involves only eight fitting parameters. The results of calculations are compared with the experimental data obtained by different authors for about 850 compositions with the use of the SciGlass information system describing the glass properties. In the temperature range 1200-2200 degrees C, the mean error of calculations for 90% of all the data available in this system is less than 0.2log eta.
