Abstract
A method of forming a cutting element for an earth-boring tool. The method includes providing diamond particles on a supporting substrate, the volume of diamond particles comprising a plurality of diamond nanoparticles. A catalyst-containing layer is provided on exposed surfaces of the volume of diamond nanoparticles and the supporting substrate. The diamond particles are processed under high temperature and high pressure conditions to form a sintered nanoparticle-enhanced polycrystalline compact. A cutting element and an earth-boring tool including a cutting element are also disclosed.
