Thermogravimetric study of the solid-phase reaction of La2-x Sr (x) CoO4 cobaltates synthesis

摘要

The course of the solid-phase synthesis of perovskite-like oxides La2-x Sr (x) CoO4 was studied by the thermal analysis method. It was found that the formation of the oxides begins above 970A degrees D after termination of thermal conversions of initial strontium carbonate and lanthanum oxide, however the final formation of ceramics is in progress up to 1400A degrees D.
