摘要： PROBLEM TO BE SOLVED: To provide SiC for efficiently producing extremely dense SiC- containing monolithic refractories which have excellent corrosion resistance, to provide a production method therefor, and to provide raw materials for the monolithic refractories. SOLUTION: The SiC for monolithic refractories has mean particle diameters of 0.01 to 3 mm, and the content of free silicon in the SiC having a particle diameter of ≤0.125 mm is, by mass, 0.01 to 0.5%. Further, the total content of free silicon and free silicic acid is 0.01 to 2% expressed in terms of free silicic acid, and the content of free carbon is 0.01 to 1.5%. In the production of the SiC, SiC is subjected to alkali cleaning, acid cleaning, carbonization, and nitriding. The raw materials for the monolithic refractories are obtained by adding alumina cement as a binder in 0.5 to 10% externally to 100% of a refractory filler having a composition containing the SiC in 5 to 80%, and the balance alumina and/or spinel.
