Patent ID: 8450228

Claim:
A refractory, in which a carbon bond is disposed between base material particles, produced by kneading a starting material containing an organic binder composed of any one of a phenol resin, tar, or pitch or a mixture thereof in an arbitrary combination, a solution or dispersion liquid of a transition metal or a transition metal salt, and alumina refractory aggregate particles and carbon based raw material which are base material particles, the solution or dispersion liquid being in a liquid state or a colloidal or suspension state in which fine particles having particle diameters of 1,000 nm or less are dispersed in a solvent, molding the kneaded product and heat-treating the molded product in a reducing atmosphere or a non-oxidizing atmosphere at 600° C. to 1,200° C., characterized in that the refractory aggregate particles are 99 to 45 parts by weight, the carbon based raw material is 1 to 55 parts by weight and, relative to them, the organic binder is 1.5 to 20 parts by weight in terms of solid content and the amount of metal in the solution or dispersion liquid is 0.01 to 1.0 parts by weight and characterized in that carbon fiber-shaped textures having diameters of 50 nm or less are contained and fine particles having particle diameters of 1,000 nm or less and containing a transition metal or a transition metal salt are dispersed in the carbon bond.
