Abstract: A lapping slurry and method of making the lapping slurry are provided. The lapping slurry comprises abrasive grains dispersed in a carrier. The carrier comprises water, ethylene glycol and between about 0.5 wt% to about 60 wt% surfactant. Abrasive particles are positively charged when dispersed in ethylene glycol having a pH in a range of from 5 to 9, as evidenced by zeta potentials.

Abstract: A superabrasive material is provided. The superabrasive material may comprise a superabrasive crystal having an irregular surface. The superabrasive material further comprises a plurality of structure defects within the superabrasive crystal or has a layered or laminar microstructure. The plurality of structure defects may cause micro- chipping when used as grinding materials. The superabrasive crystal is selected from a group of cubic boron nitride, diamond and diamod composite materials. A method of making boron nitride superabrasive materials is also provided.
