Sintering behavior of BaCe0.7Zr0.1Y0.2O3-δ electrolyte at 1150 °C with the utilization of CuO and Bi2O3 as sintering aids and its electrical performance

Perovskites for protonic ceramic fuel cells: a review

“…Up to now, in addition to the aforementioned sintering aids, multiple additives employing two complex additives have been adopted to reduce the sintering temperature of PCFC electrolytes, such as Bi 2 O 3 –CuO and BaO–CuO. 103,104 Indeed, these additives could improve the sintering of proton-conducting perovskite oxides to different degrees.…”

Influence of Triple Sintering Additives (BaO-CuO-B2O3) on the Sintering Behavior and Conductivity of the Proton-Conducting BaZr0.1Ce0.7Y0.2O3−δ Electrolyte Sintered at 1150 °C

“…The presence of the liquid phase promoted bulk diffusion, and a dense structure with a relative density of 94% was obtained . Babar et al sintered the BaCe 0.7 Zr 0.1 Y 0.2 O 3−δ electrolyte at 1150 °C using CuO-Bi 2 O 3 as a dual sintering additive . Biswas et al reported that the incorporation of nanocrystalline BaO-CuO flux with a eutectic point of 890 °C significantly enhances the sintering behavior of BZY due to the formation of a transient liquid phase and obtains BZY with a relative density of up to 97% of the theoretical density at 1300 °C .…”

Investigating the microstructural and electrochemical performance of novel La0.3Ba0.7Zr0.5X0.3Y0.2 (X = Gd, Mn, Ce) electrolytes at intermediate temperature SOFCs

“…The difference in synthesis routes can result in different morphologies (particle size, shape, and specic surface area) and conductivities of the electrolyte. 31 Based on our previous research expertise, [32][33][34][35][36][37][38][39][40][41][42][43] in the current work, we employed the combustion method to study the novel La 0.3 Ba 0.7 Zr 0.5 X 0.3 Y 0.2 (X = Gd, Mn, Ce) as a stoichiometric electrolyte material with oxalic acid and spinach as green chelating agents. This research aims to improve electrolyte conductivity at intermediate temperatures with different dopants and nd an eco-friendly (green) route to synthesize perovskite materials successfully.…”
