    Abstract: A polycrystalline compact includes diamond, cubic boron nitride, and at least one hard material, which may be aluminum nitride, gallium nitride, silicon nitride, titanium nitride, silicon carbide, titanium carbide, titanium boride, titanium diboride, and/or aluminum boride. The diamond, the cubic boron nitride, and the hard material are intermixed and interbonded to form a polycrystalline material. An earth-boring tool includes a bit body and a polycrystalline diamond compact secured to the bit body. Methods of fabricating polycrystalline compacts include forming a mixture comprising diamond, non-cubic boron nitride, and a metal or semimetal; encapsulating the mixture in a container; and subjecting the encapsulated mixture to high-pressure and high-temperature conditions to form a polycrystalline material.

    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: Superabrasive tools and methods for the making thereof are disclosed and described. In one aspect, superabrasive particles are chemically bonded to a matrix support material according to a predetermined pattern by a braze alloy. The brazing alloy may be provided as a powder, thin sheet, or sheet of amorphous alloy. A template having a plurality of apertures arranged in a predetermined pattern may be used to place the superabrasive particles on a given substrate or matrix support material.
