Oxygen exchange, thermochemical expansion and cathodic behavior of perovskite-like Sr0.7Ce0.3MnO3-δ
I. E. Kuritsyna,Vitaly Sinitsyn,A. P. Melnikov,Yu. S. Fedotov,Ekaterina V. Tsipis,Ekaterina V. Tsipis,A.P. Viskup,Sergey Bredikhin,Vladislav V. Kharton +8 more
TL;DR: The oxygen tracer diffusion and surface exchange coefficients of Sr 0.7 Ce 0.3 MnO 3-δ (SCM), measured by the 18 O/16 O isotopic exchange depth profile method with time-of-flight secondary-ion mass spectrometric analysis at 973-1123 K, are substantially higher than those of (La,Sr)MnO 3δ as discussed by the authors.
Journal ArticleDOI
Phase interaction and oxygen transport in oxide composite materials
Aliaksandr L. Shaula,Vladislav V. Kharton,Fernando M.B. Marques,Andrei V. Kovalevsky,A. P. Viskup,E.N. Naumovich +5 more
TL;DR: In this paper, the oxygen permeability of oxide composite membranes containing similar volume fractions of the components, including (La 0.9 Sr 0.1)0.98 Ga 0.8 Mg 0.2 O3-δ(LSGM) and La 0.7Sr 0.3MnO3δ (LSM), was studied at 973 −1223 K. In most cases, oxygen transport is substantially affected by component interaction, decreasing ionic conductivity due to cation interdiffusion, and formation of intermediate phases and/
Journal ArticleDOI
Site Redistribution, Partial Frozen-in Defect Chemistry, and Electrical Properties of Ba1-x(Zr,Pr)O3-δ.
Isabel Margarida Horta Ribeiro Antunes,Sergey M. Mikhalev,Glenn C. Mather,Vladislav V. Kharton,F. Figueiras,Adriana Alves,Joana Rodrigues,Maria R. Correia,Jorge R. Frade,Duncan P. Fagg +9 more
TL;DR: Changes in nominal composition of the perovskite (ABO3) solid solution Ba1-x(Zr,Pr)O3-δ and adjusted firing conditions at very high temperatures were used to induce structural changes involving site redistribution and frozen-in point defects, as revealed by Raman and photoluminescence spectroscopies.
Journal ArticleDOI
Transport and electrocatalytic properties of La0.3Sr0.7Co0.8Ga0.2O3−δ membranes
Vladislav V. Kharton,Ekaterina V. Tsipis,I.P. Marozau,A.A. Yaremchenko,Anabela A. Valente,A. P. Viskup,Jorge R. Frade,Eugene N. Naumovich,João Rocha +8 more
TL;DR: In this paper, perovskite-type La0.3Sr0.7Co0.8Ga0.2O3−δ, predominantly p-type electronic, exhibits an apparent pseudometallic behavior due to oxygen losses on heating, whereas the dependencies of the conductivity and Seebeck coefficient suggest a small polaron mechanism of hole transport.
Journal ArticleDOI
Synthesis and properties of fuel cell anodes based on (La0.5 + xSr0.5 − x)1 − yMn0.5Ti0.5O3 − δ (x = 0–0.25, y = 0–0.03)
A. I. Ivanov,D.A. Agarkov,I.N. Burmistrov,E. A. Kudrenko,Sergey Bredikhin,Vladislav V. Kharton +5 more
TL;DR: In this paper, the electrochemical properties of perovskite-like solid solutions (La0.5 + x = 0.25, y = 0−0.03) synthesized using the citrate technique and studied as oxide anodic materials for solid oxide fuel cells (SOFC) were investigated.
