The partial pressures of the components, and for the Zn‐Te system were evaluated along the liquidus curve on the basis of previously derived activities for a regular associated solution. Results are in good agreement with available experimental data. The minimum pressure of was calculated from and the free energy function, , of and the component gases. The thermodynamic data for needed for these calculations have also been critically reassessed or evaluated. By a combination of the measurements of Thomas and Sadowski with the values of along the liquidus, a retrograde solidus for was calculated. The calculated maximum solid solubility of Te in is approximately .
