The ceramics based on zinc oxide undergo doping on bismuth and antimony. Exploring the rich part of zinc in the Bi-Sb-Zn system is necessary to know the present phases. For this purpose, an experimental study was carried out by differential scanning calorimetry on alloys belonging to the isopleths

In this work we discussed the modeling of the demixing curve in the liquid state in the Lead – Zinc binary system. We are interested to recalculate the free energies relating on Pb-Zn alloys for several temperatures based on the thermodynamic data collected in the bibliography. This calculation allows us to trace the curve of phase separation from a program after obtaining the mole fractions corresponding to the common tangent to the curve of the free energy with two minima at different temperatures. To do this, we used the Matlab 7.1 as the programming language and the Redlich-Kister polynomial as a mathematical model of development. The results obtained are very satisfactory by comparing them with those of the bibliography.
