Features of Glycol-Citrate Synthesis of Highly Dispersed Oxide La0.6Sr0.4Co0.2Fe0.8O3 – δ

The features of the process of glycol-citrate synthesis of highly dispersed oxide La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3 – δ with varying concentrations of the oxidizing agent (nitro group) and reducing agent (ethylene glycol) in the reaction system have been studied. The effect of the parameters indicated...

Summary:The features of the process of glycol-citrate synthesis of highly dispersed oxide La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3 – δ with varying concentrations of the oxidizing agent (nitro group) and reducing agent (ethylene glycol) in the reaction system have been studied. The effect of the parameters indicated on the thermal behavior, spectral characteristics, phase composition, and microstructure of the obtained nanopowders has been determined. It is shown that the proposed synthesis conditions make it possible to reduce the formation temperature of single-phase highly dispersed oxides of a given composition, which are promising as cathode materials for medium-temperature solid oxide fuel cells.
