Abstract: A batch comprising, by weight, 40-80% fused alumina grain, 59-5% non-fused high alumina refractory material, and 1-15% waterinsoluble, pure Cr2O3, substantially all the discrete particles of the batch being of uniform size and averaging less than 1 m diameter, and the fused Al2O3 containing 0.5-5% TiO2, is formed into a shape and fired to give a ceramically bonded refractory shape containing at least 80% Al2O3, less than 3% SiO2 and less than 2% Fe2O3. Preferably, the fused grain is substantially all + 65 mesh (Tyler), the remainder of the batch being finely divided Cr2O3 and - 65 mesh tabular alumina and/or calcined Bayer process alumina.
