Abstract
Abrasive properties of co-fused alumina zirconia are improved by the addition of from 0.1 to 2% of Y.sub.2 O.sub.3 to the fusion mix and quenching the fused product. Y.sub.2 O.sub.3 ores containing mostly Y.sub.2 O.sub.3 with lesser amounts of rare earth oxides can be substituted for high purity Y.sub.2 O.sub.3.
