Essential content of cobalt in the mixed-oxide Sr-Ba-Fe-Co-0 system degrades its stability in reducing atmosphere, giving rise to sample destruction because of Co" reduction (metallic cobalt may be a product of this process). Insertion of additional amount of Fc203 at the end of the mechanochemical activation enhances stability of the sample, because it favors formation of amorphous layers preventing destruction. [Pg.414]

K. Although chemical stability in reducing atmosphere is improved by dopant and also conductivity increases, higher electrical conductivity in reducing atmosphere is still not enough for electrolyte of SOFCs. [Pg.1457]

The reductive (and oxidative) nonstoichiometry and the stability in reducing oxygen atmospheres of perovskite-type oxides was reviewed by Tejuca et al. [174]. Data from temperature programmed reduction (TPR) measurements indicate that... [Pg.488]

The range of the oxygen partial pressure where the rare earth doped ceria exhibits oxide anion conduction is limited over 10" Pa in P02 at 800°C (The oxide anion transference number decreased to 0.5 at this condition.), whereas the well-known stabilized zirconia shows the stable ion conduction between 10" and 10 Pa. This low stability against reducing atmosphere observed in the rare earth doped ceria is a fatal problem for applications. [Pg.242]
