<p>The present invention provides an abrasive article, particularly a cut-off wheel, having a mixture of rare earth oxide modified abrasive grains and alpha alumina seeded or iron oxide nucleated abrasive grains. Preferably, the rare earth oxide is present at a level between about 0.1 wt.% to 10 wt.% of the abrasive grain, based on a theoretical oxide basis. In one embodiment, the rare earth oxide modified abrasive grains are rods.</p> |
