    Abstract: An abrasive article can include an abrasive aggregate with the abrasive aggregate having a plurality of silicon carbide particles bonded together by a binder material. The binder material can include a vitreous phase material, a crystalline phase material, or both. In an embodiment, the crystalline phase material can include an aluminosilicate material. In a particular embodiment, abrasive aggregates can be formed from a mixture including silicon carbide particles, a binder material, and a liquid carrier. The mixture can be formed into a number of green granules that are vibrated and heated on a platen. In an illustrative embodiment, the green granules can then be heated to form abrasive aggregates.

    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 Nd 2 O 3 and Y 2 O 3 . In a particular embodiment, the abrasive particles comprise a content (wt%) of Nd 2 O 3 that is greater than a content of Y 2 O 3 (wt%).

    Abstract: An abrasive article includes a bonded abrasive body having abrasive particles contained within a bond material. The abrasive particles include silicon carbide and are essentially free of carbon-based and boron-based sintering aid materials. In an embodiment, the bond material can include a phenolic resin. In another embodiment, the bonded abrasive body can include an oxide phase disposed interstitially between the silicon carbide abrasive particles. In an additional embodiment, the abrasive particles can consist essentially of silicon carbide and aluminum oxide in a ratio of silicon carbide to alumina of at least about 8:1.
