    Abstract: A polycrystalline superhard material comprises a sintered mass of superhard grains having a mean superhard grain contiguity of at least 62 percent and at most 92 percent. There is also disclosed a method of making such a polycrystalline superhard material. The method comprises providing a precursor body comprising superhard grains and interstices between the superhard grains, and introducing additive particles into the interstices to form a pre-sinter body. The pre-sinter body is submitted to a temperature and pressure at which superhard material is thermodynamically stable, sintering it and forming polycrystalline superhard material.

    Abstract: One object of the present invention is to provide a wire drawing die excellent in strength and wear resistance. The wire drawing die has a core formed using highly hard diamond polycrystalline body made substantially only of diamond and produced by directly converting a raw material composition including a non-diamond type carbon material into diamond and sintering the diamond at an ultra high pressure and an ultra high temperature without adding a sintering aid or a catalyst, the polycrystalline body having a mixed construction including fine-grained diamond crystals with a maximum grain size of less than or equal to 100 nm and an average grain size of less than or equal to 50 nm and plate-like or particulate coarse-grained diamond crystals with a minimum grain size of greater than or equal to 50 nm and a maximum grain size of less than or equal to 10000 nm.

    Abstract: A polycrystalline diamond cutting element for use in rock drilling or other operations that requires very high abrasion resistance with high transverse rupture strength at temperatures above 700 degrees centigrade. The cutting element includes a diamond layer that contains pre-sintered polycrystalline diamond agglomerate (PPDA) bonded to a supporting substrate. The PPDA can be made thermally stable and can be selected to produce a cutting element with any desired abrasion resistance characteristic without affecting internal stress.
