Mechanical properties of LaFeO3 ceramics

Experimental set up for the mechanical characterization of plane ITM membrane at high temperature

“…The stiffness of the MIECs studied in this work seems to be sensibe to this magnetic field. This ferroelasticity effect has already been observed for LaFeO 3 by Fossdal et al [38].…”

Thermal behaviour of La0.8Sr0.2Fe1−xGaxO3−δ (x=0 or x=0.3)

“…Young's modulus evolution with respect to temperature could be dependent on the difference of ferroelastic behaviour of orthorhombic or monoclinic and the rhombohedral phase. In this way, Fossdal et al and Orlovskaya et al have shown that LaFeO 3 , 35 LaCoO 3 and La 0.8 Ca 0.2 CoO 3 perovskites 36,37 present a ferroelastic behaviour with orthorhombic-rhombohedral phase transition. Besides, Young's modulus evolution of LSFG8273 and LSF821 perovskites with temperature between 25 • C and 600 • C is similar to Young's modulus evolution of LaCoO 3 perovskites presented by Orlovskaya et al 36,37 The ferroelastic behaviour of LSFG8273 and LSF821 perovskites could be expected above the orthorhombic-to-rhombohedral phase transition described in this study by analogy with LaCoO 3 and La 0.8 Ca 0.2 CoO 3 perovskites.…”

Chemical looping methane partial oxidation: The effect of the crystal size and O content of LaFeO3

“…As oxygen carrier materials and semiconducting materials [8,9], ABO 3 perovskite-type oxides have been widely studied due to their various applications as catalyst for oxidation reactions, photocatalyst, oxygen source in membrane separation, cathode materials in solid oxide fuel cells, and gas sensors in environmental monitoring applications [10][11][12]. In the perovskite structure, the A site is typically occupied by a rare-earth element, while the B site is occupied by 3d transition metals.…”
