THERMALLY STABLE ULTRA-HARD POLYCRYSTALLINE MATERIALS AND COMPACTS
Thermally stable ultra-hard polycrystalline materials and compacts comprise an ultra-hard polycrystalline body that wholly or partially comprises one or more thermally stable ultra-hard polycrystalline region. A substrate can be attached to the body. The thermally stable ultra-hard polycrystalline region can be positioned along all or a portion of an outside surface of the body, or can be positioned beneath a body surface. The thermally stable ultra-hard polycrystalline region can be provided in the form of a single element or in the form of a number of elements. The thermally stable ultra-hard polycrystalline region can be formed from precursor material, such as diamond and/or cubic boron nitride, with an alkali metal catalyst material. The mixture can be sintered by high pressure/high temperature process.
