Oxygen permeability, thermal expansion and stability of SrCo0.8Fe0.2O3−δ–SrAl2O4 composites

“…For example, the dualphase Sr ( [17]. Additions of yttriastabilized zirconia (YSZ) in SrCo 0.4 Fe 0.6 O 3−δ yield composites consisting of three phases (perovskite, ZrO 2 and SrZrO 3 ), and enhances mechanical strength [18]. The SrFeO 3−δ -SrAl 2 O 4 composites comprising strontium-deficient SrFe 1−x Al x O 3−δ (x ≈ 0.…”

Oxygen Permeation and Stability of Ce0.8Gd0.2O2−δ–PrBaCo2−xFexO5+δ Dual–phase Composite Membranes

“…In a dual-phase composite membrane, the compositions of oxygen ionic conducting phase and electronic conducting phase can be adjusted according to different practical requirements. The fluorite structure oxides have good oxygen ion conductivity and mechanical strength, which was used as the oxygen ion conducting phase, could reduce the thermal expansion coefficient of the dual-phase membrane and increase the chemical compatibility between two phases [16,17] . Chen et al [18] researched the dual-phase membrane made of a noble metal and an oxide ionic conductor zirconia palladium (PdeYSZ).…”

Stability, oxygen permeability and chemical expansion of Sr(Fe,Al)O3−δ- and Sr(Co,Fe)O3−δ-based membranes

“…Another promising method to optimize the thermomechanical properties of mixed-conducting ceramics is the fabrication of composites. For instance, additions of alumina to SrCo 0.8 Fe 0.2 O 3 − δ and yttria-stabilized zirconia (YSZ) to SrCo 0.4 Fe 0.6 O 3 − δ were reported to enhance dimensional integrity and mechanical strength, respectively [13,14]. An improved thermal-shock resistance and fracture toughness, and reduced thermal expansion were observed for (SrFeO 3 − δ ) 1 − x (SrAl 2 O 4 ) x and (SrCo 0.8 Fe 0.2 O 3 − δ ) 1 − x (SrAl 2 O 4 ) x composite series [15,16].…”

“…An improved thermal-shock resistance and fracture toughness, and reduced thermal expansion were observed for (SrFeO 3 − δ ) 1 − x (SrAl 2 O 4 ) x and (SrCo 0.8 Fe 0.2 O 3 − δ ) 1 − x (SrAl 2 O 4 ) x composite series [15,16]. One should note that, for any composite materials, the constituent phases always interact at elevated temperatures with partial inter-dissolution of the components and/or segregation of additional phases [13][14][15][16]; the composite stability and properties are dependent on thermodynamic favorability and rate of the phase interaction.…”
