A U-shaped hollow-fiber membrane of A-site deficient K2NiF4+delta-type oxide (Pr0.9La0.1)(1.9)(Ni0.74Cu0.21Ga0.05) O4+delta ((PL)(1.9)NCG) was developed through the phase inversion spinning method. At 975 degrees C, 2.51 mL/min cm(2) oxygen permeation flux can be achieved under air/He. And stable oxygen permeation performances were obtained during the 285 h long-term tests. The electrical conductivity, surface morphology and oxygen permeation properties of (PL)(1.9)NCG hollow-fiber membrane were studied in detail.
