Polycrystalline Micron Diamond (PC) is formed by the explosive shock synthesis process as opposed to the cubic or belt press technology utilized in monocrystalline diamond synthesis. This more costly technique results in polycrystalline crystals which have more aggressive cutting properties than monocrystalline diamond. PC diamond is primarily used in engineered slurries for optical/electro-optical applications and in electronic materials lapping and polishing for productivity gains. It is often mixed with other abrasive materials to improve cut rate and/or finish.
Saint-Gobain’s 7955 and 7956 Sub-micron Polishing Slurries are
calcined aluminum oxide particles (99%+ purity) suspended in
aqueous solution, designed for use in electronics and industrial slurry
applications. They are offered with minimal additives and are intended
as the particle additive to your polishing slurry formulations.
