Title: POLYCRYSTALLINE DIAMOND COMPACT WITH SINTERING AID COMPOUND, A COMPOUND FORMED FROM A SINTERING AID COMPOUND, OR A MIXTURE THEREOF
Abstract:
The present disclosure provides a polycrystalline diamond compact (PDC) including a substrate and a polycrystalline diamond table including a sintering aid compound, a dissociated non-sintering aid component, a derivative compound, or a mixture thereof and further including dissociated sintering aid. The disclosure further provides an earth-boring drill bit containing a bit body and the PDC in the form of a cutter. The disclosure also provides a method of forming a PDC including placing a substrate and a mixture of diamond grains and a sintering aid compound in a can and performing an HTHP process to form a PDC including the substrate and a polycrystalline diamond table formed from the diamond grains and the sintering aid compound and including the sintering aid compound, a dissociated non-sintering aid component, a derivative compound, or a mixture thereof and dissociated sintering aid.
