Abstract
The values ofK ce2o2s andK ce2S3 reported in the literature are greater than they should be. Such a situation has arisen because in the calculation of the respective equilibrium constants, the total amount of Ce, O, and S each contained in the samples has been used instead of only the dissolved amounts. The relationships between equilibrium constants and temperatures of Ce-O-S, Y-O-S, Nd-O-S, La-O-S, and Ce-S in pure liquid iron have been determined by using a previously developed experimental method. The activity interaction coefficients,e /Nd-S ,e /Y-S , ande /La-S at different temperatures have been determined. The standard free energies of formation of Nd2O2S, Y2O2S, and Ce2S3 have been calculated by using the relevant experimentally derived parameters.
