ABSTRACT:
An abrasive agglomerate includes a plurality of abrasive grains bonded together in a three-dimensional structure by a substantially continuous, non-porous inorganic binder, wherein the abrasive grains have an average size of between about 0.5 microns and about 1500 microns, the inorganic binder is less than about 75 percent, by weight, of the abrasive agglomerate, and the bulk density of the abrasive agglomerate is less than about 90 percent of the bulk density of the abrasive grains.
