Resumo
The compound Ba0.50Sr0.50Co0.80Fe0.20O3–d
(BSCF) has been used as a good candidate for air electrodes in Intermediate Temperature Solid Oxide Fuel Cells.
Present work deals with the oxygen vacancy of this compound synthesized by using the EDTA–Citrate method. To
obtain a single-phase sample, three portions of the compound were calcined at 700, 800 and 900 C. Only the
sample calcined at 900 C showed a single phase. The
stoichiometry of the single-phase sample, in particular of
the oxygen atom, was determined by applying the combined X-ray and neutron Rietveld refinement to X-ray and
neutron powder diffraction patterns measured with the
sample.
