Vanadium nitride is formed during the nitriding of steel and increases wear resistance. Another phase, V2N, also referred to as vanadium nitride, can be formed along with VN during nitriding.〔''Thermo reactive diffusion vanadium nitride coatings on AISI 1020 steel'' U.Sen Key Engineering Materials vols 264-268 (2004),577〕 VN has a cubic, rock salt structure. There is also a low temperature form which contains V4 clusters.〔 〕 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. It is a strong-coupled superconductor. Nanocrystalline vanadium nitride has been claimed to have potential for use in supercapacitors. ==References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vanadium nitride」の詳細全文を読む スポンサード リンク
