摘要: Polycrystalline diamond includes cubic diamond and hexagonal diamond, and a ratio of X-ray diffraction peak intensity of a (100) plane of the hexagonal diamond to X-ray diffraction peak intensity for a (111) plane of cubic diamond is not lower than 0.01%. In addition, a present method of manufacturing polycrystalline diamond includes the steps of preparing a non-diamond carbon material having a degree of graphitization not higher than 0.58 and directly converting the non-diamond carbon material to cubic diamond and hexagonal diamond and sintering the non-diamond carbon material, without adding any of a sintering agent and a binder, under pressure and temperature conditions at which diamond is thermodynamically stable.
