Vanadium nitride is formed during thenitriding of steel and increases wear resistance.[1] Another phase, V2N, also referred to as vanadium nitride, can be formed along with VN during nitriding.[2] VN has a cubic, rock-salt structure. There is also a low-temperature form, which contains V4 clusters.[3] The low-temperature phase results from a dynamic instability, when the energy of vibrational modes in the high-temperature NaCl-structure phase, are reduced below zero.[4]
It is a strong-coupled superconductor.[5] Nanocrystalline vanadium nitride has been claimed to have potential for use insupercapacitors.[6] The properties of vanadium nitride depend sensitively on the stoichiometry of the material.[7]
