摘要：
A method of forming a substantially homogeneous suspension of nanodiamond particles and microdiamond particles is disclosed The method includes disposing a first functional group on a plurality of nanodiamond particles to form derivatized nanodiamond particles, and combining the derivatized nanodiamond particles with a plurality of microdiamond particles and a solvent to form a substantially homogeneous suspension of the derivatized nanodiamond particles and microdiamond particles in the solvent. A method of making an article is also disclosed. The method includes forming a superabrasive polycrystalline diamond compact by combining: a plurality of derivatized nanodiamond particles, a plurality of derivatized microdiamond particles having an average particle size greater than that of the derivatized nanodiamond particles, and a metal solvent-catalyst. The method also includes combining the polycrystalline diamond with a substrate comprising a ceramic. The method further includes removing a portion of a metal solvent-catalyst from the polycrystalline diamond compact by leaching.
