Abstract
A polycrystalline diamond compact formed in an in-situ boron-doped process. The in-situ boron-doped process includes consolidating a mixture of diamond crystals and boron-containing alloy via liquid diffusion of boron into diamond crystals at a pressure greater than 5 Gpa and at a temperature greater than the melting temperature of the boron-containing alloy, typically less than about 1450° C.
