Polycrystalline diamond

Polycrystalline diamond (PCD) (powder) is using a unique method of directional blasting obtained from graphite, high-explosive shock wave velocity explosive blasting

the metal slapper accelerated flight, impact resulting graphite graphite sheet into polycrystalline diamond . Its structure and the natural diamond is extremely

Similar unsaturated bond by combination with good toughness.
Applications
As a precision abrasive, for sapphire, head, disk, hard glass and crystal, ceramic and carbide ultra-precision grinding and polishing, such as for LED sapphire

thinning.
As a coating additive for metal molds, tools, parts, etc. coating, can greatly improve the surface abrasion resistance, surface hardness, long life.
Mainly used for grinding, polishing fluid preparation generally used.
May also be made knives, cutting is not prone to cracking.
