Analysis of Interfacial Processes at the SOFC Electrodes by In-Situ Raman Spectroscopy
D.A. Agarkov,I.N. Burmistrov,Fedor Tsybrov,I. I. Tartakovskii,Vladislav V. Kharton,Sergey Bredikhin,Vitaly V. Kveder +6 more
TL;DR: In this paper, a new technique for in-situ Raman spectroscopy studies of local chemical and electrochemical reactions, phase transitions, strains and morphological alterations in the SOFC electrodes under working conditions, combined with electrochemical measurements is presented.
Journal ArticleDOI
Properties of CaTi1 − xFexO3 − δ Ceramic Membranes
Filipe M.L. Figueiredo,Filipe M.L. Figueiredo,M. R. Soares,Vladislav V. Kharton,Eugene N. Naumovich,J. C. Waerenborgh,Jorge R. Frade +6 more
TL;DR: In this article, high temperature powder X-ray diffraction analysis showed a good agreement on the thermal expansion behavior of these materials between room temperature and 1000_∘C. But no evidence for surface carbonation was detected in the infrared spectra collected on samples previously annealed in CO2 atmospheres.
Journal ArticleDOI
High-temperature electrical properties of magnesiowustite Mg1 − xFexO and spinel Fe3 − x − yMgxCryO4 ceramics
Aleksey A. Yaremchenko,Andrei V. Kovalevsky,Andrei V. Kovalevsky,E.N. Naumovich,Vladislav V. Kharton,Jorge R. Frade +5 more
TL;DR: In this paper, phase relationships, thermal expansion and electrical properties of Mg1−−xFexO (x = 0.95; y = 0 or 0.5) spinels were studied at 300-1770 K in the oxygen partial pressure range from 10-Pa to 21-kPa.
Journal ArticleDOI
Mechanically-activated synthesis and mixed conductivity of TbMO4-δ (M = Zr, Hf) ceramics
Ekaterina V. Tsipis,A.V. Shlyakhtina,L. G. Shcherbakova,I. V. Kolbanev,Vladislav V. Kharton,N. P. Vyshatko,Jorge R. Frade +6 more
TL;DR: In this paper, terbium hafnate and zirconate ceramics with submicron grain sizes were prepared via mechanically-activated synthesis, and X-ray and electron diffraction and infrared (IR) absorption spectroscopy showed that TbZrO4−δ has a disordered fluorite-type structure.
Journal ArticleDOI
Mixed conductivity, stability and thermomechanical properties of Ni-doped La(Ga,Mg)O3−δ
A.A. Yaremchenko,Vladislav V. Kharton,Vladislav V. Kharton,E.N. Naumovich,E.N. Naumovich,D.I. Shestakov,V.F. Chukharev,Andrei V. Kovalevsky,Andrei V. Kovalevsky,Aliaksandr L. Shaula,Mikhail V. Patrakeev,Jorge R. Frade,Fernando M.B. Marques +12 more
TL;DR: In this article, perovskite-type LaGa 0.65 Mg 0.20 O 3− δ was characterized as a model material for ceramic membrane reactors, employing mechanical tests, dilatometry, oxygen permeability and faradaic efficiency measurements, thermogravimetry (TG), and determination of the total conductivity and Seebeck coefficient in the oxygen partial pressure range from 10 − 15 Pa to 40 kPa.
