    摘要: 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.
