PROBLEM TO BE SOLVED: To provide a dense carbon-containing brick excellent in oxidation resistance, corrosion resistance and resistance to spalling by blending a specific amount of aluminum oxycarbide as a constituting component of a carbon- containing brick. SOLUTION: This carbon-containing brick contains 3-40wt.% of a carbonaceous material and 0.5-15wt.% of aluminum oxycarbide. As the carbonaceous material, highly purified graphite is suitable in view of corrosion resistance at a high temperature. As a refractory material other than the carbonaceous material, various refractory materials such as an oxide, a carbide, a nitride or a boride formerly well-known as a refractory material can be used. Preferably, a particle size of aluminum oxycarbide is made to <=40μm. |
