    Abstract: Embodiments of the invention relate to polycrystalline diamond compacts (“PDC”) exhibiting enhanced diamond-to-diamond bonding. In an embodiment, PDC includes a sintered substantially single-phase polycrystalline diamond (“PCD”) body consisting essentially of bonded-together diamond grains exhibiting a morphology different than that of a PCD body formed by sintering diamond crystals. A substrate is bonded to the sintered substantially single-phase PCD body. Other embodiments are directed to methods of forming such PDCs, and various applications for such PDCs in rotary drill bits, bearing apparatuses, and wire-drawing dies.

    Abstract: Insert for electrical furnaces comprising an insulating shell and a coiled heater element, the heater element comprising element wire that consists of at least two sections that are interconnected via a bend of element wire in such a way that the bend and the sections mutually form a loop of element wire. A fastening member is fixedly anchored in the insulating shell and arranged in the area of the bend in such a way that the element wire in a section directly connected to the bend is prevented from expanding past the fastening member.

    Abstract: Polycrystalline compacts include smaller and larger hard grains that are interbonded to form a polycrystalline hard material. The larger grains may be at least about 150 times larger than the smaller grains. An interstitial material comprising one or more of a boride, a carbide, a nitride, a metal carbonate, a metal bicarbonate, and a non-catalytic metal may be disposed between the grains. The compacts may be used as cutting elements for earth-boring tools such as drill bits, and may be disposed on a substrate. Methods of making polycrystalline compacts include coating smaller hard particles with a coating material, mixing the smaller particles with larger hard particles, and sintering the mixture to form a polycrystalline hard material including interbonded smaller and larger grains. The sizes of the smaller and larger particles may be selected to cause the larger grains to be at least about 150 times larger than the smaller grains.

    Abstract: The invention relates to a method for manufacture of diamond, the method including the steps of providing a first coating of solvent metal or solvent metal alloy on a diamond seed to create a coated diamond seed, situating the coated diamond seed adjacent a catalyst system comprising a solvent metal and/or a source of carbon, and subjecting the coated diamond seed and catalyst system to increased temperature wherein the melting point of the first coating is at least 20 deg C. below that of the catalyst system. The invention further relates to a compact comprising a plurality of diamond seeds wherein at least one seed includes a first coating comprising a solvent metal and/or solvent metal based alloy, the compact further comprising a catalyst system comprising a solvent metal and/or a source of carbon wherein the melting point of the first coating is at least 20 deg C. below that of the catalyst system.
