Calculation of phase diagrams and thermodynamic properties of 18 binary common-ion systems of Na,K,Ba//F,MoO4,WO4

Abstract

Phase diagram and thermodynamic data of 18 binary common-ion molten salt systems in Na,K,Ba//F,MoO4,WO4 were optimized by computer algorithm. The phase diagram data as well as single-salt data were retrieved from an extensive critical literature search. Expressions for the excess properties of solution phases and thermodynamic properties of intermediate compounds were thereby obtained. These data were used to generate a "best" phase diagram for each binary system considered. Key words: molten salts, phase diagrams, thermodynamic properties.
