| Abstract: | <p> The effect of chromium on the activity coefficient of sulphur in the ternary system Fe-S-Cr has been investigated over an extended range of temperature and chromium concentrations. A levitation-melting technique was used and H2-H2S gas mixtures were passed over levitated droplets of iron and iron-chromium alloys. By comparing the experimental results obtained for both binary and ternary systems the effect of chromium on the activity coefficient of sulphur was derived in terms of first order free energy, enthalpy and entropy coefficients. Thermal diffusion effects were cancelled out by carrying out binary and ternary runs under the same experimental conditions.</p> |
