Process for the production of abrasive grains of alumina / zirconia fused material of sheet coated abrasive and polishing wheel

摘要

Abrasive properties of co-fused alumina zirconia are improved by the addition of from 0.1 to 2% of Y2O3 to the fusion mix and quenching the fused product. Y2O3 ores containing mostly Y2O3 with lesser amounts of rare earth oxides can be substituted for high purity Y2O3.
