In this work,a dual-phase material consisting of La0.7Ca0.3Cr0.95Zn0.05O3-δ(LCCZ,40 wt%) and Gd0.1Ce0.9O2-δ(GDC,60 wt%) was synthesized.Properties including phase structure,sintering behavior,electrical conducti... In this work,a dual-phase material consisting of La0.7Ca0.3Cr0.95Zn0.05O3-δ(LCCZ,40 wt%) and Gd0.1Ce0.9O2-δ(GDC,60 wt%) was synthesized.Properties including phase structure,sintering behavior,electrical conductivity and oxygen permeability for LCCZ—GDC were evaluated.The results show that dense LCCZ-GDC dual-phase disks were obtained at the sintering temperature of 1250,1300,1350 and 1400 ℃by tape casting and high temperature sintering method.The grain sizes of both GDC and LCCZ grew up with the increasing of sintering temperature.The average grain size of GDC was about 0.5,0.8,1.4,1.8 μm while the average grain size of LCCZ was about 0.8,1.5,1.8 and 2 μm after sintering at 1 250,1 300,1350 and1400 ℃,respectively.Oxygen flux of LCCZ-GDC decreased with the increase of sintering temperature from1250 to 1400 ℃.The oxygen flux of LCCZ-GDC sintered at 1250 ℃ reached 0.079 mL/min/cm2 at 975 ℃with a membrane thickness of 800 urn.Dual-phase material of LCCZ-GDC will be a promising oxygen transport membrane material for its low sintering temperature and good microstructure. 展开更多
