Oxygen permeation measurement is demonstrated, not only for a mixed oxide ionic and electronic conductor, but also as a new alternative to determine ambipolar conductivities, which can be usually reduced to be partial conductivities (either ionic or

Two materials were prepared with composition PbMg0.3-Nb0.6Zr0.1O3 (PMNZ/10) and PbMg0.32Nb0.65Zr0.03O3 (PMNZ/3). Slight modifications in lead oxide content of these materials were made to study its influence on the sintering properties. The stoichiom

A polymeric sol–gel process was developed to fabricate porous thin layers of the perovskite-type La0.3Sr0.7CoO3–δ for membrane applications. A spin-coating technique was used for deposition of the layer on porous α-and γ-Al2O3 supports. Both s

Yttria-stabilized cubic zirconia (YSZ)-palladium dual phase composites have been investigated. The percolative composite containing 40 vol% Pd (ZYPd40) showed a much larger oxygen permeability than that of the non-percolative composite containing 30
