ABSTRACT:
An improved abrasive grain comprising the sintered product of a porous non-sintered particle having a coating of inorganic material thereon is provided. A preferred method of making such abrasive grains comprises coating the porous base particles with inorganic particles. The preferred step of coating comprises a step of mixing the base particles with a suspension containing the inorganic particles in a carrier fluid. The porous base particles having the coating of inorganic particles thereon are sintered, to generate the ceramic abrasive grain product. The abrasive grains may be incorporated, to advantage, in a variety of abrasive products including for example bonded abrasives, nonwoven abrasive products and coated abrasive products.
