Vanadium oxide may refer to:

  • Vanadium(II) oxide (vanadium monoxide), VO
  • Vanadium(III) oxide (vanadium sesquioxide or trioxide), V2O3
  • Vanadium(IV) oxide (vanadium dioxide), VO2
  • Vanadium(V) oxide (vanadium pentoxide), V2O5
  • In addition to these principal oxides of vanadium, various other distinct phases exist:

  • Phases with the general formula VnO2n+1 exist between V2O5 and VO2. Examples of these phases include V3O7, V4O9 and V6O13.
  • Phases with the general formula VnO2n−1 exist between VO2 and V2O3. Called Magnéli phases for Arne Magnéli, they are examples of crystallographic shear compounds based on the rutile structure. Examples of Magnéli phases include V4O7, V5O9, V6O11, V7O13 and V8O15.
  • Many vanadium-oxygen phases are non-stoichiometric.
