Gradings | Precision size range: A narrow particle size distribution maximizes the amount of particles of the same size while fine and coarse particles are minimized. Combined with a clearly defined upper size limit, this feature allows for both high process reproducibility and superior results in surface quality. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Morphology | Rough particle surface: 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. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Synthesis | 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, superior product purity. |
