dc.description.abstract | Mixed powders of Bi2O3 and Fe2O3 are shown to yield single-phase, dense nanostructured polycrystals of
BiFeO3 in reaction flash sintering experiments, carried out by applying a field of 50 V cm 1 and with the
current limit set to 35 mA mm 2
. The furnace was heated at a constant rate with the reaction sintering
taking place abruptly upon reaching 625 C. Remarkably, an intermediate bismuth-rich phase of the oxide
that forms just before reaching the flash temperature transforms, and at the same time sinters, into singlephase BiFeO3 within a few seconds after the onset of the flash. The BiFeO3 so produced is electrically
insulating, a property that is critical to its applications. This one-step synthesis of single-phase polycrystals
of complex oxides from their basic constituents, by reaction flash sintering, is a significant development in
the processing of complex oxides, which are normally difficult to sinter by conventional methods. | es |
