Abstract: Sol-gel alumina that is dried but unfired can be explosively comminuted by feeding the dried gel into a furnace held at temperatures above those at which vaporizable materials are eliminated from the particles of gel. At suitably elevated temperatures the firing is sufficient to form fully densified alpha alumina particles of a size suitable for direct use as abrasive grits.

Abstract: A composition that can be used for abrasive processing is disclosed. The composition includes an organic bond material, an abrasive material dispersed in the organic bond material, and a plurality of microfibers uniformly dispersed in the organic bond material. The microfibers are individual filaments having an average length of less than about 1000 µm. Abrasive articles made with the composition exhibit improved strength and impact resistance relative to non-reinforced abrasive tools, and improved wheel wear rate and G-ratio relative to conventional reinforced tools. Active fillers that interact with microfibers may be used to further abrasive process benefits.
