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 product purity. |
