摘要
Nonstoichiometric Nb-substituted SrTiO3 compounds were investigated in order to discuss the influence of nonstoichiometry at the sample properties in the light of recent results reported in the literature. Structural and electrical properties of samples were characterized. Investigated compounds were also applied as anodes for Solid Oxide Fuel Cells and their reactivity with YSZ electrolyte was examined. The defect chemistry explaining observed phenomena was suggested and the probability of Sr-site vacancies formation compared to Ti-site vacancies was discussed. (C) 2012 Elsevier B.V.
