Polycrystalline Diamond Comprising Nanostructured Polycrystalline Diamond Particles and Method of Making the Same
The present invention relates to a polycrystalline diamond and a polycrystalline diamond compact comprising a continuous network of interbonded diamond constituents comprising nanostructured polycrystalline diamond particles and catalyst material located at the interstitial space among the diamond constituents, and method of making the same. The nanostructured polycrystalline diamond particles are from starting raw materials of Carbonado-type nanostructured polycrystalline diamond particles with a size of between 1 μm-40 μm. The diamond constituents may comprise micrometer-scale monocrystalline diamond particles. The catalyst material in the polycrystalline diamond or the polycrystalline diamond compact may be removed partially or completely by a leaching process. The method of making the polycrystalline diamond or the polycrystalline diamond compact comprises sintering diamond particles comprising the Carbonado-type nanostructured polycrystalline diamond particles with a size of between 1 μm-40 μm under high temperature and high pressure in the presence of the catalyst material.
