Abstract
A refractory composition consisting essentially of, for each 100 wt. % thereof, about 40 to 80 wt. % of an alumina, about 5 to 30 wt. % of a zirconia-containing grain, about 2 to 10 wt. % of a carbon, and about 1 to 12 wt. % of an oxidation and erosion resistance additive, the method of making refractory shapes utilizing such composition, and the resultant shapes.
