Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ФОТОЭЛЕКТРОННАЯ СПЕКТРОСКОПИЯ -- ТВЕРДЫЕ ЭЛЕКТРОЛИТЫ -- ГАЛЛАТ ЛАНТАНА Аннотация: The composition and chemical state of elements on the surface of solid oxygen-conducting electrolyte La0.88Sr0.12Ga0.82Mg0.18O3-α is studied by x-ray photoelectron spectroscopy before and after annealing it at 973 K in a CO2 atmosphere. Products of interaction between doped lanthanum gallate and CO2 are localized in a surface layer 8–10 nm thick. The annealing does not lead to the formation of chemical carbon compounds with metals on the electrolyte surface. Surface layers of the electrolyte both in the initial state and after the annealing are rich in strontium oxide and contain some lanthanum hydroxide Полный текст |
