Abstract

Cubic perovskite Ba_0.5Sr_0.5Co_0.8Fe _0.1R_0.1O_3-δ (R=Fe, Nb, Mo, Sb) was synthesized, and the chemical stability under high oxygen partial pressure (p(O₂)) was studied by using HT-XRD in the temperature range of 773-1373 K. It was found that Ba_0.5Sr_0.5Co _0.8Fe_0.1Sb_0.1O_3-δ was remarkably stable than Ba_0.5Sr_0.5Co_0.8Fe _0.2O_3-δ and Ba_0.5Sr_0.5Co _0.8Fe_0.1Mo_0.1O_3-δ in high p(O2) condition. The effect of B-site substitution on the CO₂- tolerance of Ba_0.5Sr_0.5Co_0.8Fe _0.1R_0.1O_3-δ was also investigated by TG-DTA analysis at 300-1373 K. It was demonstrated that the chemical stability of Ba_0.5Sr_0.5Co_0.8Fe_0.2O _3-δ against CO2 could be significantly improved when Fe were partially substituted by Nb or Sb ions.
