Properties of polycrystalline diamond powder

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 micron diamond 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.

Application of Polycrystalline Diamond Powder

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.
