Investigation of the structural and electrical properties of Co-doped BaCe0.9Gd0.1O3−δ

Formation of dense electrolytes based on BaCeO3 and BaZrO3 for application in solid oxide fuel cells: The role of solid-state reactive sintering

“…In this case, the density of all the samples was 93% and higher. Similar results were obtained in the work [80], which showed that BaCe 0.9 -x Gd 0.1 Co x O 3 -δ samples (0.01 ≤ x ≤ 0.1) with high density (more than 93%) can be prepared at 1450°С for 3 h, whereas un doped sample had a relative density lower than 90% during sintering of ceramic at 1600°С for 3 h (Fig. 6).…”

“…In the further work of these There are certain discrepancies with respect to the solubility of cobalt in materials based on BaCeO 3 and BaZrO 3 . According to the above works [65,80,82], all the cobalt containing materials were single phase. However, a continuous series of solid solutions only at 0 ≤ x ≤ 0.075 was observed in [84] for oxides BaCe 0.1 Zr 0.7 Y 0.2 -x Co x O 3 -δ produced by the solid state method at the synthesis temperature of 1100°С only at 0 ≤ x ≤ 0.075, whereas diffraction XRD the presence of a small amount of a phase based on BaCoO 3 at larger cobalt concentration.…”

Advanced materials for SOFC application: Strategies for the development of highly conductive and stable solid oxide proton electrolytes

“…It should be also noted that co-doping affects both crystalline and defective materials' structures, as well as the microstructures of ceramic samples [26,27] which affect such parameters as grain (volume) and grain boundary resistance [28][29][30].…”

A Comparative Study of Conventional and Microwave Sintering of BaCe1 − xGdxO3 − δ Ceramic

“…This study is essentially expected to contribute towards the ongoing efforts to obtain dense ceramic products from nanometric particles for SOFCs based on the application of proton conductors.
