What is Diamond Powder

Diamond micro powder is a super-hard grinding and? polishing material produced by selecting high-quality 2. single crystal artificial diamond as raw material and going through processes such as crushing, shaping, purification, classification, and post-finishing treatment.

It has high hardness, strength, toughness, thermal conductivity and thermal stability, impact resistance, etc.

Classification

Monocrystalline Diamond Powder

Monocrystalline Diamond Powder is produced from artificial diamond single crystal abrasive grains by static pressure method, which are crushed and shaped using a special process for super-hard materials.

Polycrystalline Diamond Powder

Polycrystalline diamond powder is micron and sub-micron polycrystalline particle composed of diamond grains with a diameter of 5~10nm bonded through unsaturated bonds.

Nano Diamond Powder

Detonation nano diamonds (DND) are made of carbon dissociated from explosives detonated under high temperature and pressure. They are spherical in shape without sharp edges and corners.
