Abstract
A nanoscale carbide article consisting essentially of covalently bounded elements M1, M2, and C having the molar ratio M1:M2:C::1:y:x, wherein the article has an aspect ratio of between 10 and 1000 and has a shorter axis of between 1 and 40 nanometers.
Claims2
A carbide nanorod consisting essentially of TiC, NbC, Fe3C, or BCx in which x is between 0.1 and 2.1, inclusive, wherein said nanorod has an aspect ratio of between 11 and 1000, and has a shorter axis of between 1 and 40 nanometers.
A carbide nanorod consisting essentially of covalently bonded elements M1, M2 and C having the molar ratio M1:M2:C::1:y:x,
- wherein said first element M1 is tungsten, molybdenum, zirconium, hafnium, vanadium, tantalum, chromium, manganese, technetium, rhenium, osmium, cobalt, nickel, a lanthanide series element, scandium, yttrium, or lanthanum;
- said second element M2 is nitrogen, boron, phosphorus, zinc, aluminum, copper, germanium, cadmium, indium, tin, lead, thallium, or the elements in said first element group, in which y is between 0 and 0.9, inclusive, provided that said first and second element are not the same;
- and
- said third element C is carbon, in which x is between 0.1 and 2.1, inclusive;
- wherein said nanorod has an aspect ratio of between 11 and 1000, and has a shorter axis of between 1 and 40 nanometers.
