Sr- and Mg-doped LaGaO3 powder synthesis by carbonate coprecipitation

Low-temperature sintering and electrical properties of strontium- and magnesium-doped lanthanum gallate with V2O5 additive

“…Until now, the sintering temperature has been decreased either by employing innovative consolidation techniques [14][15][16][17][18][19] or by preparing easily sinterable powders [20][21][22][23][24][25][26]. The design of sintering aids to promote densification can be a practical alternative.…”

Electrochemical reduction of CO 2 in solid oxide electrolysis cells

“…Lanthanum gallates-based perovskite oxides (ABO 3 ) doped by Sr in La (A) sites and Mg in Ga (B) sites respectively, forming La 1 −x Sr x Ga 1 −y Mg y O 3 −δ (LSGM), show high oxygen ionic conductivity [30] . For example, the oxygen ionic conductivity of La 0.9 Sr 0.1 Ga 0.8 Mg 0.2 is 0.15 S/cm at 1073 K, which is comparable to that of ceria-based oxygen ionic conductors and significantly exceeds that of YSZ.…”

Effect of synthesis methods on the Ca3Co4O9 thermoelectric ceramic performances

“…In this work it will be shown the comparison between three different synthesis methods which produce precursor powders with very high surface/volume relationship. These methods have already been used previously in other systems: coprecipitation with ammonium carbonate (as reported for LaGaO 3 in [22]), coprecipitation with oxalic acid (as reported for BaSnO 3 in [23]), and attrition milling (as reported for Bi 2 Sr 2 CaCu 2 O x in [24]), using the solid state route as reference. A very important advantage of the two first methods is the intimate mixture of cations in the precipitate, which allows obtaining very pure final products.…”
