Synthesis and characterization of Sr- and Mg-doped LaGaO3 by using glycine–nitrate combustion method

Technological development of hydrogen production by solid oxide electrolyzer cell (SOEC)

“…It can be seen that the conductivity is quite sensitive to the doping content and the optimal doping content is about 15 mol%. It should be noted that the optimal doping content reported by various groups are different because of different starting materials used and different preparation procedures employed [42,43]. This may cause formation of secondary phase during the preparation process.…”

Nanometric La0.9Sr0.1Ga0.8Mg0.2O3−x ceramic prepared by low-pressure reactive spark-plasma-sintering

“…Very often the resulting LSGM ceramic contains impurity phases. To remove impurity phases, long reaction times (typically 10-40 h) and high temperatures (>1400 • C) are required [2,3]. Especially this seems to be the case when applying conventional sintering on calcinated (oxide) reacted precursors.…”

Electrochemical Investigation of LSGMC-Composite Cathodes on LSGM-Substrate

“…In recent years, Sr-and Mg-doped LaGaO 3 (LSGM) perovskite materials have gained considerable attention as potential electrolytes for intermediate temperature (IT) SOFCs. Many of the reported LSGM compositions exhibited ionic conductivity at 800ºC (3)(4)(5)(6) higher or comparable to that of YSZ at 1000ºC. The highest electrical conductivity, 0.17 S/cm at 800ºC, was achieved with La 0.8 Sr 0.2 Ga 0.8 Mg 0.2 O 3−δ by Ishihara et al (7).…”
