Abstract
A polycrystalline diamond and a polycrystalline diamond compact comprise nanostructured polycrystalline diamond particles (aggregates) and binder material. The nanostructured polycrystalline diamond particles (aggregates) are from starting raw materials of nanostructured polycrystalline diamond particles (aggregates) with a size of between 1 μm-40 μm. The polycrystalline diamond and the polycrystalline diamond compact may comprise micrometer-sized monocrystalline diamond particles. The binder 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 nanostructured polycrystalline diamond particles (aggregates) with a size of between 1 μm-40 μm under high temperature and high pressure in the presence of the binder material.
