The refractory, e.g. an Al2O3-C, MgO-C, or MgO-Al2O3-C refractory, is provided with excellent oxidation resistance and hot strength by including both boron carbide and powder comprising at least one of Al, Si, Fe, and Ni. The refractory comprises, by weight, 3 to 30 parts of graphite, 79 to 97 parts of refractory raw materials, 1 to 7 parts of the said powder, and 0.3 to 5 parts of boron carbide. |
