Embodiments disclosed herein relate to cell assemblies for fabricating superhard materials (e.g., used in a high-pressure cubic press) and methods of using the same. The disclosed cell assemblies include a plurality of internal anvils, at least some of which are positioned internally relative to a cell pressure medium of the cell assembly. Such a configuration for the cell assemblies may enable one or more of intensifying cell pressure, reducing processing time, or reducing costs for fabricating such superhard materials.

Cell assemblies and methods of using the same

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.
