Abstract
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 
.
