An equilibrium study of the system Bi-S-H₂

Author

Abstract

"An experimental study has been conducted to determine the equilibrium behavior of the system Bi-S-H₂. The system was studied by equilibrating H₂-H₂S gas mixtures with Bi(l)- Bi₂S₃(s) two-phase mixtures at temperatures of 500°, 600°, 700° and 750°C in a circulating type equilibrium apparatus. The equilibrium gas mixtures were analyzed by a Fisher Gas Partitioner with a reproducibility of approximately 0.06 %.

A linear free energy equation has been derived from the results with an average deviation of ± 1 Kcal. This deviation is well within the accepted experimental accuracy for free energy data.

The linear free energy equation for the reaction, Bi₂S₃(s) + 3 H₂(g) = 2 Bi (1) + 3 H₂S(g)

was calculated to be,

ΔF⁰_T = 20,800 - 32.8 T ± 1 Kcal

The activity of sulfur in liquid bismuth-sulfur alloys has been determined by analyzing the alloys which were equilibrated with H₂-H₂S gas mixtures at temperatures of 500°, 600°, 700° and 750°C"--Abstract, page ii.
