Abstract

An abrasive article includes a body having abrasive particles contained within a bond material. The abrasive particles can include a majority content of silicon nitride and a minority content of sintering material including at least two rare-earth oxide materials. In an embodiment, the rare-earth oxide materials can include Nd2O3 and Y2O3. In a particular embodiment, the abrasive particles comprise a content (wt%) of Nd2O3 that is greater than a content of Y2O3 (wt%).
