Abstract

Diamond compact composed of 60-95 volume % diamond crystals plastically deformed into a closely packed, rigid structure with contacts between the diamond crystals over extended mating surfaces arising from the plastic deformation. The diamond crystals are bonded together by an interstitial bonding material composed of a refractory carbide, such as silicon carbide, or a bonding material composed of a metal such as rhenium and a refractory carbide formed by reaction of a metallic bonding agent, such as tungsten, with carbon.
