Thermodynamic description of the Cu–Pb–Zn system

Thermodynamic description of the ternary Cu–Pb–Zn system is presented. The adjustable parameters of the sub-systems, Cu–Pb, Cu–Zn and Pb–Zn, are taken from earlier SGTE-based assessments and those of the ternary system are optimized in this work using the experimental zinc activity and phase equilibrium data.
