La2Zr2O7 formation and oxygen reduction kinetics of the La0. 85Sr0. 15MnyO3, O2 (g)| YSZ system

A Mitterdorfer, LJ Gauckler - Solid State Ionics, 1998 - Elsevier
Nucleation and growth of lanthanum zirconate (LZO) between (001) single crystals of 9.5
mol% Y203-stabilized ZrO2 (YSZ) and porous La0. 85Sr0. 15MnyO3±δ (y= 0.95… 1.10)
perovskites were investigated. The perovskites were screen-printed on the solid electrolyte
and sintered in air at 1373 K for short periods. High resolution transmission electron
microscopy, electrochemical impedance spectroscopy, and atomic force microscopy were
employed for interface characterization. The manganese concentration in the perovskite …
