| Примечания: | Title screen Iron oxides, especially well-known magnetite (Fe3O4) and relatively new ?-Fe2O3 phase, attract a scientific and practical interest due to their unique magnetic properties. Despite the large number of known methods for synthesizing Fe3O4, obtaining the ?-Fe2O3 phase is still remaining an urgent scientific task. This paper presents the studies on the possibility of controlled synthesizing the pointed out iron oxide phases in a single short-term high-energy plasma dynamic process. It is established that the process energy directly affects the phase composition of obtained iron oxides. At higher energies, the products are characterized with the dominance of the ?-Fe2O3 phase (up to ?65?wt %) presented in the form of nanosized crystallites, while at low energies micron-sized hollow spherical particles attributed to Fe3O4 are synthesized (up to ?75?wt %). By optimizing the synthesis process it is possible to reach the ?-Fe2O3 phase yield up to ?90?wt %. The change in the phase composition depending on the initial energy parameters directly affects the magnetic characteristics and magnetic behavior of the synthesized iron oxide products.
