Abstract

The effects of Nb doping on the chemical stability of Ba 0.5Sr0.5Co0.8Fe0.2O 3 - δ based solid solutions under high oxygen partial pressure (p(O2)) and CO2-containing atmospheres were studied. BSCF and Ba0.5Sr0.5Co0.9Nb0.1O 3 - δ (BSCN) and Ba0.5Sr0.5Co 0.8Fe0.1Nb0.1O3 - δ (BSCFN) were prepared and investigated by using TG-DTA analysis under p(O2) = 1 and 10- 3 bar with or without CO2. The results showed that the Nb substitution effectively improved the chemical stability under high oxidation condition and also improved the CO2-tolerance of BSCF-based materials.
