THE THERMODYNAIC PROPERTIES OF MELTS OF THE SYSTEM MgO – Al2O3 – SiO2, MgO – CaF2 – SiO2, Al2O3 – CaF2 – SiO2

Abstract

Abstract. Method of forecasting thermodynamic properties of melts from the liquidus coordinates ofphase diagram in the area of equilibrium of a solid component with a solution is presented. Gibbs mixingenergies in the binary boundary MgO – Al2O3, MgO – SiO2, MgO – CaF2, Al2O3 – SiO2, Al2O3 – CaF2,SiO2 – CaF2 systems are calculated by this method.Keywords: a activity, coordinates of liquidus, the diagrams of the state, the double and triple systems, theequalization of Hauffe-Wagner, the melts, the partial molar energy of Gibbs, the thermodynamics properties.
