Vaporization of the system MgO-Al 2O 3-SiO 2 in the temperature range 1770-1890 K was studied and activities of MgO and SiO 2 were determined. Activities of the components, isothermal sections of the phase diagram, and the position of the liquidus line in the studied system were calculated using the Gay-Kapoor-Frohberg model. The correlation of the found values of thermodynamic properties and phase equilibriua in isothermal sections of the phase diagram of the studied system was illustrated.
