Influence of the preparation conditions on the synthesis, structure and thermal properties of LaSrCo1-xMnxO4 [PDF]

open access: yesJournal of the Serbian Chemical Society, 2006
A series of LaSrCo1-xMnxO4 (x=0.1, 0.3, 0.5) mixed oxides with a perovskite-type structure were successfully synthesized at fairly low temperatures in air by the decompositon of amorphous citric and ethylene diamine tetraacetic acid complexes.
