Strength and Elastic Modulus of Lanthanum Strontium Cobalt Ferrite Membrane Materials

摘要: Abstract Mixed ionic electronic ceramic transport membranes have a large potential for industrial oxygen supply and carbon emission reduced fossil power plant concepts. Although permeation phase stability are main development aspects, mechanical robustness is of concern especially the long term performance reliability under application relevant thermo-mechanical loads. Lanthanum strontium cobalt ferrite materials appear to be advantageous, with respect CO 2 stability. However, effect A-site stoichiometry on properties needs assessed. Furthermore, advanced design concepts rely thin layers supported by porous substrate therefore also porosity an important factor. Hence, these aspects were investigated dense La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3− δ 0.38 0.62 . The specimens using ring-on-ring bending set-up. work summarizes compares temperature dependencies elastic moduli fracture stresses.
