Thermodynamic calculation of phase diagrams of the 60 common-ion ternary systems containing cations Li,Na, K,Rb, Cs and anions F,Cl, Br,I

The phase diagrams of all 60 possible common-ion ternary alkali halide systems were calculated thermodynamically. The thermodynamic properties of the ternary phases were calculated from the optimized properties of the binary subsystems, which were obtained from previously reported critical evaluations of binary data. Calculated ternary phase diagrams are compared with experimental diagrams in those 47 systems for which the latter are available. In most cases, agreement is within experimental error limits. For five systems, a small empirical correction term was added to the Gibbs energy expression in order to bring the calculated and reported diagrams into coincidence. The calculated ternary diagrams are considered to be the best evaluated diagrams that can be deduced from currently available data. A probable maximum inaccuracy was estimated for each system.     

Thermodynamics and phase diagrams of 32 binary common-ion systems of the group Li,Na,K,Rb,Cs//F,Cl,Br,I,OH,NO3

Published thermodynamic and phase diagram data for 32 systems of the group Li,Na,K,Rb,Cs//F,Cl,Br,I,OH,NO₃ were evaluated by a computer-coupled thermodynamic/phase diagram method. In all cases, thermodynamically smoothed phase diagrams were calculated as were excess properties of solution phases and fusion properties of intermediate compounds.
