      abstract     = {Ce0.8Gd0.2O2-δ-FeCo2O4 composite is an excellent oxygen
                      transport membrane material with good chemical stability for
                      applications in oxygen separation and membrane reactors. To
                      improve microstructural and mechanical properties, sintering
                      profiles for Ce0.8Gd0.2O2-δ-FeCo2O4 composites were
                      optimized. Different sintering temperatures are selected
                      based on our study of phase interactions among the initial
                      powder mixtures using high-temperature X-ray diffraction.
                      The results reveal that the phase interaction at ∼1050 ℃
                      accelerates densification process, and a further increase of
                      sintering temperature to 1200 ℃ contributes to the
                      homogenization of the pore distribution. A higher density
                      and an improved homogeneity of pore distribution result in
                      enhanced mechanical strength. However, the density decreases
                      once the sintering temperature reaches 1350 ℃. Hence, the
                      optimal sintering temperature considering both
                      microstructural and mechanical properties appears to be 1200
                      ℃. Sintering at this temperature results in a
                      microstructure with a density exceeding 99 $\%$ with only
                      small surface defects and a high average flexural strength
                      of approximately 266 MPa.},
