A sintered material based on silicon carbide (SiC) reactively sintered between 1,100° C. and 1,700° C. to form a silicon nitride binder (Si<SUB>3</SUB>N<SUB>4</SUB>), intended in particular for fabricating an aluminum electrolysis cell, including 0.05% to 1.5% of boron, the Si<SUB>3</SUB>N<SUB>4</SUB>/SiC weight ratio being in the range 0.05 to 0.45. Application, in particular, to an electrolysis cell.
