Abstract
Perovskite powders of La0.3Sr0.7CoO3-delta were prepared by the therma l decomposition of precursor complexes derived from nitrate solutions using ethylenediaminetetraacetic acid (EDTA) as a complexing agent. Th e calcination temperature is 920 degrees C. Powders thus obtained have a low carbon contamination. Dense ceramics with a relative density of about 96% have been prepared after sintering at 1150 degrees C.
