The invention relates to a sintered material having an average chemical composition such that, in weight percentages on the basis of the oxides: Cr2O3 <= 80.0-99.0%; 0.5% <= TiO2 <= 9.0%; 0.2% <= MgO <= 3.0%; and ZrO2 <= 5.0%, provided that the molar ratio of TiO2/MgO is between 1.5 and 9.0 and the molar ratio of TiO2/Cr2O3 is less than 0.12.
