DIATRON PTR POLYCRYSTALLINE DIAMOND POWDERS

DIATRON PTR are very friable diamond that does not perform well in a high impact application.  However, this polycrystalline diamond abrasive is synthetically designed to provide highest cutting action with its multi-faceted sharp edges that replenish itself during use through micro-fracturing.  The most common application is in precision polishing of hard substrates such as sapphire, SiC, GaN, AlN, and other optical crystals and industrial ceramics.

Applications

• Hard electronic substrates: Sapphire, GaN, SiC, Ge, AlN
