Polycrystalline diamond powder is constituted through the unsaturated linkage nano

It is different from the production of nano-detonation single crystal diamond. Hardness of single crystal diamond having a directivity, its crystal structure, crystal morphology, internal defects and crystal size. The polycrystalline diamond powder is connected to  cutting tools  bond,  Diamond blade  "aggregate polycrystalline particles," they are isotropic, no cleavage plane. Not only has the unmatched  abrasive wheels  and strength, but also has high toughness, and thus overcome the static pressure (mechanical top pressure) synthesized single crystal diamond material is easily brittle cleavage plane and detonation diamond soft reunion and other shortcomings.
