Fe-Zr-O system was studied with X-ray Radial electronic density distribution (RED) method. It has been demonstrated that samples have near structure closely related to that of cubic alfa-ZrO2. Some structural models of samples were considered. The model with statistical arrangement of Fe3+ cations, vacancies in the cation and anion sublattices and modification of anion sublattice with OH- groups is admitted as most probable. Numbers of cation and anion vacancies and number of OH- groups were calculated for the model using experimental RED curves of samples.
