Abstract

See full text

Ceramic aggregate particles comprising a plurality of solid particulates bonded together by ceramic binding material and methods of providing a plurality of such particles having substantially uniform cross-sectional shape are provided. The ceramic aggregate particles may incorporate a high percentage of solid particulates. The ceramic binding material may closely conform to the outermost surfaces of the solid particulates contained within the ceramic aggregate particle. When abrasive particulates are employed as the solid particulates, abrasive articles can be made which provide consistent high cut rates and consistent surface finish over relatively long periods of time.
