Abstract: Polycrystalline diamond compacts (“PDCs”) and methods of manufacturing such PDCs. In an embodiment, the PDC includes a polycrystalline diamond (“PCD”) table having at least a portion of a metal-solvent catalyst removed therefrom. Removing at least a portion of a metal-solvent catalyst from the PCD table may increase the porosity of the PCD table relative to a PCD table that has not been treated to remove the metal-solvent catalyst. Likewise, removing at least a portion of a metal-solvent catalyst from the PCD table may decrease the specific magnetic saturation and increase the coercivity of the PCD table relative to a PCD table that has not been treated to remove the metal-solvent catalyst.
