Abstract
A method of making a dense diamond body comprises the steps of: forming a sintered polycrystalline diamond body with the use of a catalyst; forming voids in the body by removing at least some of the catalyst; and reducing the overall volume of voids by applying pressure and temperature to the body in a vessel substantially free of additional catalysts.
