In the spinel system FeV2O4-ZnV2O4 pure Fe(II)-spinels could not be prepared. Mössbauer spectra show that the solid solution has the composition Fex2+ Zn1-x:[Fey3+ V2-y]O4, y depending on the partial pressure of oxygen during preparation. The reaction of 1/3 Fe + 1/3 Fe2O3 + V2O3 in a closed tube was also studied by X-ray and Mössbauer investigation.
