Detonated Polycrystalline Diamond Micron Powder For Semiconductor
0-1um to 8-12um Detonated Diamond Lapping Powder for Semiconductor
Description:
Polycrystalline diamond, is synthesized by detonation method. The color is grayish black, slightly metallic; It is composed of nano-crystallites that give it a unique break down mechanism, which allows new cutting edges to be exposed creating a self-sharpening characteristic. In the application, nano-crystallites break down gradually, resulting in more crystal edges and grinding surfaces. Therefore, polycrystalline diamond has the characteristics of high removal rate, self-sharpening and high toughness, which not only ensures the surface finish of workpieces, but also improves the grinding efficiency, it shows its unique superiority in the processing of some high quality products.
