The chemical composition of the catalyst powder of diamond

Diamond powder catalyst is generally used in powder 200-300 mesh, graphite, pressed into the diamond catalyst and catalyst in the process of transition metal elements of the 3d electron state of atoms, polycrystalline diamond synthesis under high grinding wheel and temperature are basically using transition metals as a catalyst, such as iron-based or nickel-based. Shift from the basic synthetic diamond of the diamond, the iron-based catalyst design more in line with the diamond structure corresponds catalyst, and soluble carbon bond orientation principle. Therefore, from the process and production cost considerations, a large number of diamond powder catalyst is some iron-based powder.
