1. A method of forming metal carbide fibers, the method comprising:
reacting a carbon fiber material with at least one of a metal or metal oxide source material, selected from the group consisting of aluminum, beryllium, calcium, cerium, chromium, dysprosium, erbium, europium, gadolinium, hafnium, holmium, iron, lanthanum, lithium, magnesium, manganese, molybdenum, niobium, neodymium, praseodymium, samarium, scandium, tantalum, terbium, thorium, titanium, tungsten, uranium, vanadium, ytterbium, yttrium, zirconium, aluminum oxide, beryllium oxide, calcium oxide, cerium oxide, chromium oxide, dysprosium oxide, erbium oxide, europium oxide, gadolinium oxide, hafnium oxide, holmium oxide, iron oxide, lanthanum oxide, lithium oxide, magnesium oxide, manganese oxide, molybdenum oxide, niobium oxide, neodymium oxide, praseodymium oxide, samarium oxide, scandium oxide, tantalum oxide, terbium oxide, thorium oxide, titanium oxide, tungsten oxide, uranium oxide, vanadium oxide, ytterbium oxide, yttrium oxide, zirconium oxide and combinations thereof, at a temperature greater than: the melting temperature of the metal or metal oxide source material; or the vaporization temperature of the metal or metal oxide source material; so as to produce a metal carbide fiber as the carbon fiber material is converted to metal carbide by reaction with the at least one of a metal or metal oxide. |
