Effect of microstructure on chemical stability and electrical properties of BaCe0.9Y0.1O3 − δ

Abstract: Y-doped barium cerate BaCe 0.9 Y 0.1 O 3 − δ was synthesised by a solid-state reaction method. Materials with different average grain sizes and grain boundary surface areas were obtained. The effect of microstructure on the chemical stability in the CO 2 and H 2 O-containing atmosphere and electrical properties was analysed and discussed. To evaluate the chemical stability of BaCe 0.9 Y 0.1 O 3 − δ , the exposure test was performed. Samples were exposed to the carbon dioxide and water vapour-rich atmosphere at… Show more

“…One of the fundamental property of this type of perovskite materials is their pure stability in atmosphere containing carbon dioxide and water vapor. [11][12][13] This factor is especially important for materials that would potentially work in hydrocarbon environment due to a possibility of oxidation of organic carbon to carbon dioxide. Compared to ceranes, titanates, they exhibit higher chemical stability (in CO 2 and H 2 O atmosphere) and, what is more, strontium titanate is one of the most stable representatives of this perovskite group.…”

“…The processing of the spectra was carried out by a circuit of series-connected resistance R el and three parallel-connected RQ chains. The high-frequency response in the spectrum with a characteristic frequency of 1.5-2 MHz in the wet and dry air, respectively, and with a characteristic capacitance value of~10 -8 F, as widely accepted, refers to the grain boundaries of the electrolyte [33,34]. The electrode response with a characteristic capacitance of~10 −4 F and a characteristic frequency of 1-8 kHz probably refers to oxygen diffusion in the electrode.…”

“…In another work, Lacz 13 studied the chemical stability of BCY10 toward CO 2 and H 2 O with a comparative exposure test (7% CO 2 in air, 100% RH at 25 • C, 700 h). In this work, mass spectrometry results showed traces of both barium hydroxide and barium carbonate resulting from decomposition.…”
