supply polycrystalline diamond

详情

Polycrystalline micron diamond powder is an explosion-synthesized micron diamond powder. Due to its polycrystalline structure, it has no well defined cleavage planes. It can therefore bear pressures 2 to 3 times higher than monocrystalline diamond. In addition, its particles have a specific surface area 2 to 3 times higher than monocrystalline diamond, which gives them a higher abrasive power due to their many contact points and cutting edges. Through its high cutting power, polycrystalline micron diamond powder is unchallenged in the lapping and polishing of composite materials, on which it produces very flat surfaces, without any unevenness between hard and soft areas. Key features: Polycrystalline structure Shock synthesized graphite based Micro-fractures during use exposing new surfaces Multi-edged particles are shaped and graded to very close tolerances Texturing, precision lapping, microelectronics, metallographic. Ideal for magnetic heads and selective lapidary work
