Product features: fine particles, no agglomeration, narrow particle size distribution and high purity.
Advantage: machining accuracy in Å will not cause scratches by reason of agglomeration, and the close tolerance control of particle will keep danger away from unwanted impurities.   
With fast and high-quality processing, it reduces scratchescaused by a wide distribution of particles.
Main applications: infrared materials (Ge, ZnS, ZnSe) contact lenses, precision alloy (tungsten-aluminum-copper alloy wiring materials and thin-film materials in intermediate layer of integrated circuit), tiny precision ball bearing, optical steel mold, speculum, electron optics, laser crystal, natural stone, artificial gemstones and other materials.
