Zusammenfassung:A superabrasive particle, such as cubic boron nitride, and method of making the same are disclosed. A cubic boron nitride particle may have an irregular surface, wherein the surface roughness of said particle is less than about 0.95. The method for producing abrasive particles having a unique surface morphology may comprise the steps of providing a plurality of abrasive particles; blending reactive metal powder with the abrasive particles; compressing the blended components into a pellet; heating said pellet; and recovering modified abrasive particles.
