Polycrstalline - This black powder is produced through a shock synthesis process which uses controlled explosions. EID Polycrystalline Micron Diamonds feature a unique polycrystalline structure that facilitates controlled microfracturing. This super abrasive resists major cleavage fractures and its high toughness allows it to tolerate three times higher operating pressures than monocrystalline diamond.
It is recommended for lapping and finishing sapphire, ruby, ferrite's, ceramics and other non-metal oxides.
Our premium grade, suitable for high-end engineering and most precision finishing applications.
This special grade is the preferred choice for customers working with micro sensitive finishing applications such as sapphire boules and high-end optical components.
