| 中文摘要 | Uniform nanopowders of La0.6Sr0.4CoO3−ı (LSC)were synthesized by the combined citrate–EDTA method.The precursor solution was prepared from nitrates of the constituent metal ion, citric acid and EDTA with a pH value controlled by ammonia. The obtained product was characterized by TG/DTA, XRD, SEM, and BET measurements. The single perovskite phase could form completely after sintering at the temperature of 900℃. There was no significant effect of the precursor solution pH value on the perovskite phase formation temperature; however, LSC powders prepared from the precursors with different pH values showed specific shapes. The morphology of La0.6Sr0.4CoO3−δ powder was also optimized with proper surfactant addition. The sintered La0.6Sr0.4CoO3−δ bulk samples exhibited an electrical conductivity of 1867Scm−1 in air at 800℃. The impedance spectra of a symmetric LSC cathode on a GDC electrolyte substrate were measured and polarization resistance (Rp) values of 0.17Ωcm2 at 700℃ and 0.07Ωcm2 at 750℃ in air were obtained. |
