FG micron diamond powder is preferred in applications where high performance and reproducibility are required. FG micron diamond powder is available as diamond powder and as ready-to-use diamond suspension.
Particle strength: The high toughness of polycrystalline diamond tolerates three times higher operating pressures than monocrystalline diamond. This allows for significantly higher material removal rates compared to other diamond types.
Self-sharpening: During the lapping process, the applied pressure causes single crystallite grains to break away from the particle. Fracturing exposes new, sharp cutting edges. This self-sharpening of the particle allows for continuously high abrasion rates.

FG micron diamond powder is ideal for lapping applications requiring a high stock removal and a controlled surface finish. Typical applications include lapping and polishing of sapphire, synthetic gemstones, ceramics, tungsten carbide, soft and hard metals.
Standard size range: The standard size range makes this product suitable for applications that focus primarily on cost. The controlled upper-limit ensures a uniform, scratch-free surface quality.
The micro-structured, rough particle surface provides numerous contact points between diamond particles and the work piece. This feature ensures high material removal rates even in processes with low specific pressure, such as polishing processes on soft cloths or pads.
Polycrystalline diamond is formed by detonation synthesis. The ultra-short synthesis time yields diamond particles with a polycrystalline structure. Each diamond particle consists of countless primary crystals of approximately twenty nanometers in size. The rough particle surface and the high particle strength of polycrystalline diamond are characteristic features of polycrystalline diamond synthesis. Proprietary shaping and cleaning processes guarantee a uniform, blocky particle shape and a controlled product purity.
