Tellurium Thermodynamics in Austenitic Iron
McDermid, J. R.
A two-zone furnace arrangement was used to determine the solubility of tellurium vapour in γ-iron foils at 1273 and 1548 K. Liquid tellurium held at a lower temperature generated Te (g) and Te2 (g) at a known partial pressure which was equilibrated with foils held at a higher temperature. Knowledge of the two temperatures allowed the calculation of the activity of tellurium with respect to the solid reference state. Analysis of the equilibrated foils allowed the calculation of the infinite dilution activity coefficient of tellurium which is expressed as a function of temperature.
