Abstract
A method of forming polycrystalline diamond includes providing an alloy over diamond particles and subjecting the diamond particles to a pressure of at least 4.5 GPa and a temperature of at least 1,000° C. to form inter-granular bonds. The alloy includes iridium and at least one of copper, silver, and gold. A polycrystalline diamond compact includes diamond grains bonded by inter-granular bonds and an alloy disposed within interstitial spaces. The alloy includes iridium, carbon, and at least one of copper, silver, and gold. An earth-boring tool includes a bit body and a polycrystalline diamond compact secured to the bit body. Some methods include selecting an alloy that is catalytic to formation of diamond-to-diamond bonds when the alloy is in a liquid phase, but non-catalytic to the back-conversion of diamond to graphite at temperatures of less than about 1,000° C.
