Vanadium nitride, VN, is a chemical compound of vanadium and nitrogen.
Vanadium nitride is formed during the nitriding 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 in supercapacitors. [6] The properties of vanadium nitride depend sensitively on the stoichiometry of the material. [7]
