“…The model reproduces the sulfur activity data of Fosnacht et al [91] very well and reproduces well the data of Rosenqvist [20] and Grigorovich et al [88] The calculated liquidus is in good agreement with the experimental points. [92,93] …”

“…The sulfur activity data in the metal-rich region [29,30,35,89,90] are scattered but are generally in good agreement. The sulfur activity measurements of Fosnacht et al [91] with the H 2 S/H 2 equilibration method cover the composition range from pure cobalt to 50 at. pct S and agree with most of the other data.…”

“…The optimization is based on the sulfur activity data of Fosnacht et al [91] and Rosenqvist [20] in the liquid and on the liquidus data of Friedrich [92] and Hülsmann and Weibke. [93] The following parameters were obtained by optimization: 6 ϭ Ϫ73,450 Ϫ 94,948Y ϩ 1,032,980Y J/mol [30] CoS S S ϭ Ϫ12.000Y J/mol⅐K [31] CoS S…”

The modified quasichemical model for short-range ordering is described for liquid metal-sulfur solutions. Available thermodynamic data for molten Fe-S, Ni-S, Cu-S, and Co-S solutions are collected, critically evaluated, and optimized by means of the model. Very good descriptions of the thermodynamic properties are obtained with few parameters. Using only these binary parameters, the model predicts the thermodynamic properties of Fe-Ni-S, Fe-Cu-S, Ni-Cu-S, and Fe-Ni-Cu-S mattes over a wide range of composition and temperature within experimental error limits.
