Abstract
Mass loss occurs in Cr2O3 when it is exposed to steam at 923 K for 0.5 Ms or 1.3 Ms. The presence of S at an impurity level of 23 ppm in the oxide suppresses the mass loss by about a half. For example, for the 0.5 Ms exposure, the mass loss is about 0.055% in pure Cr2O3 but about 0.030% in S-doped Cr2O3. This result is related closely to our previous result that the existence of 50 ppm S in high Cr ferritic steels causes a tremendous improvement in the steam oxidation resistance at 923 K.
