ABSTRACT
The measurements of vapor-liq. equil. (VLE) for Cu-Bi and Cu-Bi-Sb alloys in vacuum distn. were performed. We calcd. the VLE diagrams of Cu-Bi and Cu-Bi-Sb alloys at 10 Pa by Wilson equation only using binary parameters. Thermodn. consistency tests of exptl. data for the binary and ternary systems were discussed using the Van Ness method. The calcd. results are in good agreement with the exptl. data. The VLE data can be used for designing the purifn. process and phase sepn. of crude copper in vacuum metallurgy.
