Abstract

The chemical compatibility of perovskite-type Ba_0.5Sr _0.5Co_0.8Fe_0.2O_3-δ (BSCF) oxides with Cr₂O₃ has been examined between room temperature and 1,100 °C. Differential thermal analysis and thermogravimetric analysis were used to analyze the thermal behavior of BSCF-Cr₂O₃ binary mixtures in all composition ranges (0-100 mass% BSCF). The reaction products were identified by X-ray analysis after heating at 700-1,100 °C. As we expected, it was found that perovskite-type BSCF oxide had a poor chemical compatibility with the Cr ₂O₃ oxide. In particular, the decomposition process of the BSCF-Cr₂O₃ binary mixture is quite complex and it starts at about 700-750 °C. The mixtures of BSCF and Cr₂O₃ oxides reacted forming mixed complex oxides based on (Ba/Sr)FeO₃, (Co/Fe)CrO₄, and (Ba/Sr)CrO₄ mixtures.
