Fused spinel-zirconia grains and refractory product obtained from said grains
Fused grains, in which the grains include a matrix of the zirconia-spinel eutectic coating inclusions composed essentially of a zirconia phase or of a spinel phase, the grains exhibit the following overall chemical composition, as percentages by weight expressed in the form of oxides: more than 45.0% and less than 95.0% of ZrO2, more than 3.0% and less than 40.0% of Al2O3, more than 1.0% and less than 20.0% of MgO, wherein ZrO2, Al2O3 and MgO together represent at least 95.0% of the weight of the grains.
