Abstract
Sulfur solubility in pure Cr2O3 was measured over a large range of oxygen (10−6−10−12 atm) and sulfur (10−2 -10−16 atm) partial pressures at 1273 K. Different methods of analysis were used; it was found that the neutronactivation technique produced the most reliable and reproducible results. The results obtained showed that the limiting solubility of sulfur in Cr2O3 varied between 16–93 ppm for the range of oxygen and sulfur pressures used in this study. The solubility was found to vary, depending on the combined effect of\(P_{O_2 } \) and\(P_{S_2 } \). For a given\(P_{O_2 } \), the amount dissolved increases with an increase of\(P_{S_2 } \). An empirical equation,\([S] = P_{O_2 }^{0.030} P_{S_2 }^{0.066} \) was found to best fit the experimental results and indicates a stronger influence of\(P_{S_2 } \) than of\(P_{O_2 } \). A specific dissolution mechanism connot be formulated from this equation. However, a number of possibilities have been proposed, but none of these specific mechanisms seems to fit the experimental data.
