A Computer Assessment of the Ru-Rh and Ru-Pd Systems

Abstract

Optimized phase diagrams of the Ru-Rh and Ru-Pd systems were calculated using thermodynamic coefficients derived by the assessment of available experimental phase diagram and thermodynamic data. The excess Gibbs free energies of the phases are described employing the ordinary polynomial expressions in regular or subregular models. The temperatures of various transitions and the composition limits of the phases are reproduced closely.
