Product Description

Polycrystalline Diamond Micron Powder

Detonation Polycrystalline Diamond Powder
Blasting polycrystalline diamond powder is formed by detonation synthesis.
The high self-sharpening ability for continuously high abrasion rates while producing the smoothest, scratch-free surface possible. During the lapping process, the applied pressure causes grains to break away from the particle. Fracturing exposes new, sharp cutting edges.
The high particle strength and high toughness of polycrystalline diamond powder allow for significantly higher material removal rates.
Precision size range, narrow particle size distribution, and high purity these features allow for superior results in surface polishing quality.

Similar Polycrystalline Diamond Powder
Similar polycrystalline diamond powder is formed by the surface corrosion treatment.
The same advantages as blasting polycrystalline: high self-sharpening ability, high material removal rate, narrow particle size distribution, low scratch count, and excellent surface polishing results.
Compared with blasting polycrystalline diamond powder, the similar polycrystalline diamond powder can save nearly two-thirds of the cost, which is very economical.

Polycrystalline Diamond Micron Powder Applications

1. As a precision abrasive, it is used for ultra-precision grinding and polishing of silicon wafers, sapphire, magnetic heads, hard disks, hard glass and crystals, ceramics, and hard alloys.
2. As a coating additive, it is used for coating metal molds, tools, parts, etc., which can greatly improve surface wear resistance, surface hardness, and extend service life.
3. Make resin bond, ceramic bond, and metal bond diamond tools to improve the grinding efficiency of the tool, increase the holding power of diamond and bond, and prolong the service life.
4. It is mostly used in the production of diamond slurry for grinding and polishing silicon wafers, sapphire, ceramics, optical glass, etc.
