COMPOSITE ABRASIVE PARTICLES AND METHOD OF MANUFACTURE

摘要

The present application discloses an agglomerate. The agglomerate comprises a crystalline matrix. The agglomerate may additionally comprise abrasive particles. The agglomerate has a normalized bulk density of less than about 0.38. The present application additionally discloses a method of manufacturi ng the agglomerate. The agglomerate is manufactured by forming a mixture comprising an abrasive particle with a sol, the sol comprising an oxide and water and introducing the mixture into a spray dryer. The mixture is then dried in the spray dryer. The mixture is then fired, for example in an oven. The resulting agglomerates comprise abrasive particles retained within a crystalline matrix of the oxide. The present invention additionally disclose s methods of using the agglomerates of the resent invention.
