Poly (Polycrystalline Diamond Powder)

Properties
Detonation-synthesized polycrystalline diamond 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 micron diamond 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.
