Diamond Powders and Superabrasive Grains

Diamond powders and superabrasive grains include extreme-hardness abrasives such as synthetic diamond, natural diamonds, and cubic boron nitride (CBN). They are used in the polishing, finishing, grinding, and cutting of ultra-hard materials such as ceramics, stone, glass, superalloys, and titanium. Diamond powders and superabrasive grains have very high hardness values and are sometimes used in the processing of optics. Natural diamond is the hardest mineral while synthetic diamond is the hardest man-made material. Cubic boron nitride (CBM) is second to diamond in terms of hardness.
