  • Detonation-synthesized polycrystalline diamond micro-powder
  • The structure resembles the rare natural polycrystalline black diamond, metallic-grey, superior toughness, self-sharpening.
  • The lapping and polishing efficiency of the detonation-synthesized polycrystalline diamond micro-powder is 2 to 4 times better compared with that of the mono-crystalline diamond that is naturally occurred or synthesized via the static pressure method, Silicon Nitride, Corundum, and other abrasive materials.
  • Polycrystalline diamond micro-powder allows the manufacturing of the smoothest surface possible:
a.  When using polycrystalline diamond micro-powder of size 2-4micron to the polishing surface, Ra(roughness)<1.6nm
b.  When using polycrystalline diamond micro-powder of size 0-0.5micron to the polishing surface, Ra(roughness)<1.3-1.4nm
c.  When using polycrystalline diamond micro-powder of size 0-0.125micron to the polishing surface, Ra(roughness)<0.1nm
  • polycrystalline diamond can maintain its dull mono-crystalline structure by releasing the outer layer, hence will produce the most scratch free surface possible.
  • When applied to the surface of a workpiece (for example, the inner surface of a cylinder in an engine) via chemical plating method, the wearability of the surface is superior to that of a surface treated with any other materials.
  • Via after-sinter technique, polycrystalline diamond micro-powder can be turned into polycrystalline diamond particles of a large size that are highly valuable in a variety of industries.


  • Lapping and polishing a variety of surfaces that require superior smoothness.
  • Improving the wearability of a mechanical component
  • Via after-sinter technique can be applied in a variety of industries.
  • Can be made into liquid abrasives, gel abrasives, and many other types of abrasive tools that are capable of ultra-fine lapping and polishing tasks.


Polycrystalline diamond micron powder can be used for below industries:
  • Computer industry: Read/Write head lapping, rigid disk media texturing
  • Gem polishing
  • Semi-Conductor, electronic ceramic, optical instruments
  • Used as anti-wearing media in special rubber and plastics
  • Chemistry catalyst, Biomedicine
