Alumina-magnesia product for gasifier or for metallurgical furnace
The invention relates to a melted and cast refractory product having a chemical composition such that, in mass percentages on the basis of the oxides: AI2O3: complement up to 100%; MgO: 26% to 50%; ZrO2: 0.5% to 10.0%; B2O3: <1.5%; SiO2: ≦0.5%; Na2O+K2O: ≦0.3%; CaO: ≦1.0%; Fe2O3+TiO2: <0.55%; other oxide species: <1.0%. In said product, the elementary mass ratio R of the zirconium content to the total boron, fluorine and silicon content is between 2 and 80.
