Vanadium(III) nitride, VN, is a chemical compound of vanadium and nitrogen. Vanadium(III) 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] It is a strong-coupled superconductor. [4]
Nanocrystalline vanadium nitride has been claimed to have potential for use in supercapacitors [5]
