The composition, especially for a refractory brick for lining rotary kilns in the cement industry, is based on magnesia spinel, having a content of 10 to 50 % by weight of spinel clinker (MgO.Al2O3), 50 to 90 % by weight of sintered magnesia and a content of 0.5 to 4 % by weight, relative to the total quantity of spinel clinker and sintered magnesia, taken as 100 % by weight, of a metal oxide which promotes attachment, the metal oxide being zirconium oxide in a grain size range of < 0.1 mm; a refractory brick is produced using such a refractory composition. <IMAGE> |
