Nanocrystalline niobium carbide (NbC) was successfully synthesized at 550 °C by using a co-reduction route. X-ray powder diffraction and X-ray photoelectron spectra confirmed the formation of cubic NbC. Transmission electron microscopy image revealed that typical NbC crystallites are composed of uniform particles having an average size of about 30 nm. Thermogravimetric analysis showed that the oxidation of nanocrystalline NbC occurred between 350 and 550 °C.
