Since in recent years, LED and other industries the application of new technologies in the field continues to expand, polycrystalline diamond powder usage has grown significantly, increasing demand.

Product performance:

A. Detonation synthesis of polycrystalline diamond powder having expensive and rare black natural diamond of the polycrystalline structure, is dark gray, metallic luster, good toughness, there's automatic edge features.

B. Detonation synthesis of polycrystalline diamond with the impact of synthetic static pressure or natural single crystal diamond, silicon oxide, corundum and other abrasive compared to polycrystalline diamond, grinding efficiency is higher 2 to 4 times.

C. Polycrystalline diamond grinding accuracy to an unprecedented increase.

a, In the use of 2 ~ 4µm of polycrystalline diamond powder polishing of the workpiece, R<1.6 nm.

b, Using 0 ~ 0.5 µm polycrystalline diamond powder for grinding a workpiece, Ra=1.3 to 1.4 nm.

c, In the use of the 0 to 0.125 µm polycrystalline diamond powder for grinding a workpiece, Ra<0.1 nm.

D. Due to the polycrystalline diamond surface,“the mission ball”shape, it is polished surface, will not leave scratches, thereby improving the milling yield.

E. Polycrystalline diamond powder also can be prepared by chemical plating method, the plating on the workpiece(such as cylinder)of the inner wall, the wear resistance is superior to any other material.

Polycrystalline diamond powder uses:

A. The polishing of sapphire, silicon, ceramic, metal, etc.

B. Machining the magnetic Head material, anti-magnetic film(MR), a multi-layer film, a sputtering film, a molecular beam epitaxy(MBE), the ferrite and the printing plate.

C. Processing fiber optic connectors, laser rod and requires a certain optical waveguide through the other products.
