Thermodynamic modeling of the Pb + Bi melt evaporation under various pressures and temperatures

Abstract

The composition of the vapor phase and the partial pressures of vapor components have been defined at pressures from 102 to 107 Pa and in the temperature range from 500 to 3000 K. 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. © 2012 Elsevier B.V. All rights reserved.
