Abrasive - an overview | ScienceDirect Topics

Abrasive ceramic materials are critical in the grinding, lapping, and polishing operations that enable the production of parts requiring high-dimensional tolerances. The sharp abrasive grains must necessarily be harder and tougher than the material being cut so that they do not round off or fracture during contact.
