<P>PROBLEM TO BE SOLVED: To provide a monolithic refractory which has an excellent spalling resistance, improved oxidation and corrosion resistances, high heat conductivity and high strength. <P>SOLUTION: The monolithic refractory contains a refractory comprising coarse particles, intermediate-sized particles and fine particles, and an alumina cement. The monolithic refractory contains 20-90 mass% of a composite material of silicon carbide and silicon nitride. The composite material contains at least one selected from among the group consisting of Al, Ca, Fe, Ti, Zr and Mg in an amount of 0.1-8 mass% in terms of oxide. <P>COPYRIGHT: (C)2008,JPO&INPIT |
