Ultra Detonated Polycrystalline Micron Diamond Powder Grade HID PD
HID PD Ultra Detonated Polycrystalline Diamond Powder for polishing
Description:
Industrial synthetic diamond powder is a new type of super-hard abrasive, which is mainly used for manufacturing tools used in the process of processing high-hardness and high-precision articles in industrial production.
Currently, it is generally used for polishing from w0-0.5 to w6-12. W15-10 to w22-36 for grinding; W12-22 coarse for fine grinding.
It has the following important features:
- Strictly control the size classification
- Uniform particle shape characteristics
- Control raw materials
Polycrystalline Diamond (HID PD) is a new type of high-technology materials in 21st century,which is a polymer of nano diamond produced by means of detonation at transient state with ultra higher pressure and temperature and resemble"carbonado" in the rare natural meteoric stones.
HID PD is a polycrystal consisting of cubic diamond and hexahedron diamond.It has higher toughness and higher hardness as well,as a new type of abrasive it is unchallenged and irreplaceable in the lapping and polishing of sapphire substrate.
Polycrystalline micron diamond powders are consisted of nano-crystallites that give it a unique break down mechanism which allows new cutting edges to be exposed creating self-sharpening characteristics. Because of its polycrystalline nature, HID PD has no defined cleavage planes. It can therefore tolerate 3 times higher operating pressure than monocrystalline diamond. Another major advantage of HID PD is the diamond particles have a specific surface with much more contact points and cutting edges,and producing the most scratch free surface possible and superior finish as well.
