BINARY ALKALINE-EARTH OXIDE MIXTURES - ESTIMATION OF THE EXCESS THERMODYNAMIC PROPERTIES AND CALCULATION OF THE PHASE-DIAGRAMS

A survey of available experimental excess thermodynamic properties far the binary alkaline earth oxide mixtures is given. The known excess t hermodynamic properties of the oxide mixtures are evaluated and missin g values are estimated by analogy with the binary common-ion alkali ha lide mixtures. The phase diagrams of the oxide mixtures corresponding to the evaluated / estimated excess properties are calculated and comp ared with the available experimental phase diagrams.
