Abstract: Niobium carbide composites were obtained by sintering niobium powder and detonation nanodiamond at high pressure (7GPa) and high temperature (∼1990°C) for several tens of seconds. The resulting composites demonstrate a set of distinct reflections from the NbC phase in the X-ray diffraction pattern and exhibit superconducting properties at temperatures below 11.4K.

Keywords: niobium, detonation nanodiamond, sintering at high pressure, superconducting composite, electron microscopy, X-ray diffraction, magnetochemistry, magnetic studies.
