Claim Text:
1. A method for forming a refractory metal carbide component, the method comprising the steps of: providing a refractory metal nanoparticle mixture, the refractory metal nanoparticle mixture including a solvent and a plurality of refractory metal nanoparticles, each of the plurality of refractory metal nanoparticles being surrounded by a layer of surfactant molecules in which the surfactant molecules are bonded to a surface of the refractory metal nanoparticles; disposing the refractory metal nanoparticle mixture in a mold; heating the refractory metal nanoparticle mixture to a first temperature to evaporate the solvent and leave the plurality of refractory metal nanoparticles surrounded by the surfactant molecules and bonded thereto in the mold; and heating the plurality of refractory metal nanoparticles and the surfactant molecules while in the mold to a second temperature to thermally decompose the surfactant molecules and to react the plurality of refractory metal nanoparticles with carbon from the decomposed surfactant molecules to provide a refractory metal carbide component.
