Abstract
A method for making polycrystalline diamond material comprises providing a plurality of diamond particles or grains, coating the diamond particles or grains with a binder material comprising a non-metallic catalyst material for diamond, consolidating the coated diamond particles or grains to form a green body, and subjecting the green body to a temperature and pressure at which diamond is thermodynamically stable, sintering and forming polycrystalline diamond material.
