Zusammenfassung:PURPOSE:To obtain the title refractory brick excellent in corrosion resistance, by constituting the refractory brick of aluminum nitride oxide, graphite, SiC, components selected from Al, silicon and B4C and alumina based raw material at specific ratios. CONSTITUTION:For example, a phenolic resin, as necessary, is added and kneaded with a raw material mixture of 30-50wt.% coarse, medium or fine particulate aluminum nitride oxide, 3-20wt.% fine particulate graphite, 3-15wt.% fine particulate SiC, 0-6wt.% one or components selected from fine particulate Al, silicon and B4C and the remainder of coarse, medium or fine particulate alumina based raw material. The resultant kneaded material is press formed and dried to afford the title refractory brick having the composition of the above-mentioned blending ratio.
