Abstract
A coated abrasive article includes a backing and fused alumina-zirconia abrasive grains attached to the backing with a binder. The fused alumina-zirconia abrasive grains include between about 35 wt % and about 45.5 wt % ZrO2+HfO2, between about 43.7 wt % and about 65 wt % Al2O3, less than about 0.8 wt % SiO2 and less than about 10 wt % other oxides. The fused alumina-zirconia abrasive grains simultaneously satisfy both a granulometric and densimetric condition.
