Abstract
A method for rapidly synthesizing polycrystalline diamond, includes the steps of machining a large monolithic graphite piece, placing the starting graphite piece in direct contact with an activator piece composed of a nickel-base alloy, and subjecting the contacting pieces to high static pressure and high temperature for a time sufficient to cause the starting monolithic graphite piece to undergo complete transformation into diamond to yield monolithic polycrystalline diamond.
