Abstract
This study reports the interfacial stability of doped (La0.8Sr0.2)0.95Cr0.7Fe0.3O3 (LSCF) and 10Sc1CeSZ system in oxidizing and reducing atmosphere for the application of oxygen transport membrane (OTM) device. Role of oxygen partial pressure (PO2) on the interfacial stability of LSCF with 10Sc1CeSZ is studied under OTM fabrication conditions (1400°C, PO2 ~0.21–10−10atm). Interfacial stability corresponding to the interaction between LSCF and 10Sc1CeSZ decreases with decrease in PO2. Interfacial study of LSCF with 10Sc1CeSZ shows absence and presence of strontium zirconate (SrZrO3) at the interface in oxidizing (PO2 ~0.21atm) and reducing atmosphere (PO2 ~10−10atm) at 1400°C respectively. Mechanism for the formation of SrZrO3 is reported.
