摘要：

Lanthanum strontium cobalt iron oxides, with the perovskite structure, were synthesised using citrate and glycine complexation methods. Low temperature calcination of the precursor phases leads to the formation of cubic perovskites, which on high temperature calcination form rhombohedrally distorted perovskites. The cubic phase is identified as a perovskite, La0.6Sr0.4-xCo0.2Fe0.8O3-delta with a large degree of strontium deficiency (x = 0.20 to 0.25).
