摘要： The present invention provides a carbon-containing refractory composition characterized by containing 0.1-10 parts by weight of silicon hexaboride in 100 parts by weight of refractory material comprising 3-95 parts by weight of carbonaceous material such as graphite and 97-5 parts by weight of refractory aggregate.In the carbon-containing refractory composition of the present invention, silicon hexaboride is oxidized producing boron oxide on the surface of the refractory at a high temperature during operation, and the surface of the refractory is covered by the formation of a highly viscous molten liquid like kotoite (3 MgO.B.sub.2 O.sub.3), for example, which is formed from the components of the refractory, such as MgO, for example, thus particles of carbonaceous material such as graphite can be protected from oxidation.The present invention therefore provides a refractory that has superior oxidation resistance which can be effectively utilized in such fields as metallurgy, pig iron production, steel production, etc.
