Structural, Sintering and Electrical Properties of Cr-doped La0.6Sr0.4CrxFe1-xO3-δ （x=0.10, 0.20） Oxides
The perovskite Cr-doped La0.6Sr0.4CrxFe1-xO3-δ （x=0.10, 0.20） oxides were synthesized via the citrate gel method. The perovskite forming of the Lao.6Sr0.4CrxFel-xO3-δ （x=0.10, 0.20） oxides were studied by ther- mogravimetric analysis （TG）, differential scanning calorimetry （DSC）, and X-ray diffracti...

| description | The perovskite Cr-doped La0.6Sr0.4CrxFe1-xO3-δ （x=0.10, 0.20） oxides were synthesized via the citrate gel method. The perovskite forming of the Lao.6Sr0.4CrxFel-xO3-δ （x=0.10, 0.20） oxides were studied by ther- mogravimetric analysis （TG）, differential scanning calorimetry （DSC）, and X-ray diffraction （XRD）. Structural and chemical stability under H2-containing helium atmospheres of Lao.6Sro.4CrxFel-xO3-δ （x=0.10, 0.20） were investigated by TG and XRD. The sintering microstructures of the perovskite Lao.6Sr0.4Cr2Fel-xO3-δ （x--0.10, 0.20） ceramics were investigated by scanning electron microscopy （SEM）, and the electrical conduc- tivities of both oxide ceramics were also measured up to 900℃. The results demonstrated that the chemical stability of the Co-free Lao.oSro.4CrxFe1-xO3-δ （x=0.10, 0.20） oxides was significantly improved compared to the Co-containing Lao.6Sr0.4C00.2Fe0.8O3-δ and Ba0.5Sr0.5Co0.8Fe0.2O3-δ oxides. The incorporation of Cr cations in the B-site of the pervoskite oxides resulted in the improved structural and chemical stability of the as-synthesized Lao.6Sr0.4CrxFe1-xO3-δ （x=0.10, 0.20） oxides. |
