GRISH detonation Nano-diamond (DND), also called Ultra-fine diamond (UFD), is made from the dissociative carbon in High pressure and temperature during detonation by Oxygen-Negative Explosive. It is different from the Synthesized diamond, the shape of DND is sphere without sharp edges and the micro crystal size is about 4-7nm.

GRISH Monocrystalline Diamond powder is made of high quality diamond through crushing, shaping, grading and other processes. Monocrystalline Diamond powder has sharp edge and high hardness.

GRISH detonation polycrystalline diamond powder (PCD) is produced in a controlled explosion. Grains microscopic structure is similar with natural Carbonado.

GRISH Rough-surface Monocrystalline diamond powder, RCD for short, derived from monocrystalline diamond powder processed by a special technology. RCD Powder is more like polycrystalline diamond on performance. Compared with monocrystalline diamond powder, RCD powder has a rougher surface, which acts as a large number of small cutting chins. It can both reduce surface roughness and enhance removal rate of the workpiece.

GRISH Diamond-bead Powder is composed of micron sized diamond beads, and each bead is formed by much smaller micron sized diamond particles. During polishing process the diamond beads break into smaller particles, which perform as polishing chain and provide consistent polishing and achieve longer life. The special microstructure gives good perfor-mance, such as self-sharpening, continuous polishing force, and high removal rate with less scratches on the finish surface.

GRISH have three kinds of ultra fine polishing powder Silicon Carbide, Aluminum Oxide and Cerium Oxide produced by advanced grading technology. They are characterized with high purity, excellent crystal shape and uniform particle size distribution. These are mostly used by optics, communications, display, semiconductor, data storage industry and etc.
