Vanadium oxide
From Wikipedia, the free encyclopedia
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.[1]
- Phases with the general formula VnO2n−1 exist between VO2 and V2O3.[1] Called Magnéli phases for Arne Magnéli[2], they are examples of crystallographic shear compounds based on the rutile structure.[1] Examples of Magnéli phases include V4O7, V5O9, V6O11, V7O13 and V8O15.
Many vanadium-oxygen phases are non-stoichiometric.[2]
