Abstract
Improved carbon-containing, chemically bonded, refractory compositions, usually magnesia or alumina base, including about 1% to 20% by weight carbon and about 0.5% to 10% by weight steel fibers, low carbon steel fibers, or stainless steel fibers of about 10-50 mm in length and about 0.1 mm to about 1.0 mm in diameter of any cross-sectional shape distributed in the carbon-bearing matrix and bonded thereto. Other fibers compatible with both the intended application and the base composition may also be used.
