A carbon-containing refractory is formed by mixing 1-10 weight % of silicon nitride, 1-35 weight % of carbon, and a remainder of a refractory raw material, molding the mixture into a molded body, and burning the molded body such that fine whiskers of silicon carbide are uniformly distributed within the matrix.

Carbon-containing refractory and a manufacturing method therefor

A carbon containing refractory comprising, by weight: 5 to 60% of AZT clinker mainly constituted by ZrO.sub.2, Al.sub.2 O.sub.3, TiO.sub.2 and SiO.sub.2 ; 3 to 40% of a carbon source; and the balance being at least one or two refractories selected from a group consisting of alumina, magnesia, zirconia, mullite, spinel, calcia, and fused quartz.
