Chromium oxide product
A sintered refractory product having a granulate bonded by a matrix and comprising, in percentages by mass based on the oxides, —more than 40% chromium oxide Cr2O3, —less than 50% aluminium oxide Al2O3, −1% or more zirconium oxide ZrO2, of which at least 20% by mass is stabilised in the cubic and/or quadratic form, −0.1% or more yttrium oxide Y2O3, acting as a stabiliser for the zirconium oxide ZrO2, —less than 1.9% hafnium oxide HfO2, the total content of chromium, aluminium and zirconium oxides Cr2O2+Al2O3+ZrO2 being greater than 70%.
