Patent ID: 8297382

Claim:
A polycrystalline diamond compact, comprising: a polycrystalline diamond table, at least an un-leached portion of the polycrystalline diamond table including, a plurality of diamond grains defining a plurality of interstitial regions; a metal-solvent catalyst occupying at least a portion of the plurality of interstitial regions, the metal-solvent catalyst present in an amount of about 1 weight % to about 6 weight %; and wherein the plurality of diamond grains and the metal-solvent catalyst collectively exhibit a coercivity of about 115 Oersteds (“Oe”) or more and a specific magnetic saturation of about 15 Gauss·cm 3 /grams (“G·cm 3 /g”) or less; wherein the polycrystalline diamond table exhibits a G ratio of at least about 4.0×10 6 ; and a substrate including an interfacial surface that is bonded to the polycrystalline diamond table, the interfacial surface exhibiting a substantially planar topography.
