"Solid state reaction of Bi2O3 · Fe2O3 mixtures was shown to yield impure bismuth ferrate, BiFeO3, containing Bi2Fe4O9 and residual Bi2O3; this places the results of much of the literature based on BiFeO3 prepared by this technique in suspect. Single phase polycrystalline BiFeO3 was prepared by multiple nitric acid leaching of sintered samples which contained excess Bi2O3 to prevent the formation of Bi2Fe4O9 during sintering. X-ray and neutron powder diffraction data indicate that …
