Description
Summary:► The TERRA soft and the ISIP model have been used. ► Composition and partial pressure of the Pb–Bi vapor phase have been defined for different pressures and temperatures. ► Diagrams of phase equilibriums for the liquid–steam Pb–Bi system have been constructed. ► A good correlation between experimental results and the carried out calculations on the Pb–Bi phase diagrams is observed. The composition of the vapor phase and the partial pressures of vapor components have been defined at pressures from 102 to 107Pa and in the temperature range from 500 to 3000K. Diagrams of liquid–vapor phase equilibria for the Pb–Bi system have been constructed. A good agreement between experimental results and the carried out calculations on the Pb–Bi phase diagrams is observed.
