Structural properties of mixed conductor Ba_1−xGd_1−yLa_x+yCo₂O_6−δ

Abstract

Ba1-xGd1-yLax+yCo2O6-δ (BGLC) compositions with large compositional ranges of Ba, Gd, and La have been characterised with respect to phase compositions, structure, and thermal and chemical expansion. The results show a...

A modified DC Hebb–Wagner polarization method for determining the partial protonic electrical conductivity in mixed-conducting BaGd0.3La0.7Co2O6−δ

“…It has previously been shown that BGLC undergoes a phase transition from a Pmmm a2b2c to a Pmmm 2a3b3c supercell upon hydration. 38 The supercell contains some oxygen sites with a favourable environment for proton formation and may thus act as traps limiting proton mobility. Fig.…”
