An uncontrollable removal of halogen-ions from oxides during synthesis was detected. Nevertheless, residual halogens were found to provide a notable impact on ion conductivity and oxide stability under reducing conditions. More than twice higher ion conductivity relative to SrFeO 3– δ was recorded in materials with nominal compositions SrFeO 2.8– δ F 0.2 , SrFeO 2.6– δ Cl 0.4 , and SrFeO 2.4– δ Cl 0.6 . The strong effect of halogen addition on ceramic properties of oxides was revealed. While SrFeO 3– δ was known for its poor sinterability, adding 0.2 mol of fluorine or chlorine during the synthesis of SrFeO 3– δ was shown to result in successful obtaining gas-tight ceramics.","claims":[{"public_id":"cl_c4c2c0cdc8daa1af36e178847f137a52","status":"active","text":"Adding 0.2 mol of fluorine or chlorine during synthesis enables successful preparation of gas-tight
