Synthesis and Characterization of Ln0.6Sr0.4Fe1-χCoχO3-σ for ITSOFC
Source abstract
Abstract
The powders of Ln0.6Sr0.4Fe1-χCoχO3-σ (Ln=La, Pr, Nd, Sm and Gd) were obtained by solid state reactions. The cell parameters of the specimens were analysised by XRD. The change in mass and oxygen stoichiometry of the samples as a function of temperature was determined by TGA. The electrical conductivity of the sintered samples was measured as a function of temperature from 100 to 1000℃. It shows that the electrical conductivity of all these samples is higher than 100S/cm, especially the electrical conductivity of Nd0.6Sr0.4Co0.8Fe0.2O3-σ can be up to 600S/cm, and all the samples possess good chemical compatibility with Ce0.8Gd0.2O1.9 at 1200℃ for 24h.
