PROBLEM TO BE SOLVED: To obtain a refractory capable of having high corrosion resistance, scarcely causing cracking and excellent in durability. SOLUTION: This Cr-containing refractory consists essentially of A12O3 and comprises Cr2O3 in an amount of 10-40% expressed in terms of weight ratio and a softener capable of softening at >=1,000 deg.C in an amount of 5-10% expressed in terms of weight ratio. The softener is preferably soda-lime glass. An oxide, a nitride, a carbide or a boride of Al, Mg, Zr and/or Si, e.g. spinel, zircon, mullite or forsterite can further be contained in the Cr-containing refractory. |
