1. A method of forming polycrystalline diamond, comprising:
forming metal nanoparticles having a carbon coating from an organometallic material; combining a diamond material with the metal nanoparticles having the carbon coating; and processing the diamond material and the metal nanoparticles having the carbon coating to form the polycrystalline diamond, including:
catalyzing formation of the polycrystalline diamond by the metal nanoparticles; andforming interparticle bonds that bridge the diamond material by carbon from the carbon coating, wherein the organometallic material is a metallocene comprising: a metal selected from magnesium, aluminum, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, zirconium, ruthenium, hafnium, tantalum, tungsten, rhenium, osmium, or a combination comprising at least one of the foregoing; and a ligand selected from an alkyl, aryl, hydride, halide, amide, η2-alkene, CO, CS, amine, nitrile, isocyanide, phosphane, alkylidene, alkyldiide, nitrene, imide, oxide, alkylidyne, alkytriide, η3-allyl, η3-enyl, η3-cyclopropenyl, NO, η4-diene, η4-cyclobutadiene, η5-cyclopentadienyl, η6-arene, η6-triene, η7-tropylium, η7-cycloheptatrienyl, η8-cyclooctatetraene, or a combination comprising at least one of the foregoing. |
