Abstract:
Embodiments of the invention relate to polycrystalline diamond compacts (“PDCs”) and methods of fabricating polycrystalline diamond tables and PDCs in a manner that facilitates removal of metal-solvent catalyst used in the manufacture of polycrystalline diamond tables of such PDCs.

Claim (Index 1):
A subterranean drill bit, comprising:\n a bit body; and a plurality of polycrystalline diamond compacts affixed to the bit body, at least one of the plurality of polycrystalline diamond compacts, including:\n a substrate; and \n a polycrystalline diamond table including a working surface and an opposing interfacial surface bonded to the substrate, the polycrystalline diamond table including bonded diamond grains defining a plurality of interstitial regions, the polycrystalline diamond table further including:\n a first volume extending inwardly from the working surface; \n a second volume extending inwardly from the interfacial surface; \n a metal-solvent catalyst and at least one sacrificial material disposed in at least a portion of the plurality of interstitial regions; \n wherein the at least one sacrificial material includes a material different than that of the metal-solvent catalyst; \n wherein the at least one sacrificial material is present in the first volume in a concentration such that the first volume exhibits a concentration of the metal-solvent catalyst of less than 0.85 weight % of the first volume after leaching the first volume.
