Abstract

$Ba_{0.5}Sr_{0.5}Co_{0.8}Fe_{0.2}O_{3-{\delta}}$ hollow fiber with o.d. 1.02 mm and i.d. 0.437 mm were fabricated by a phase-inversion spinning technique.The starting $Ba_{0.5}Sr_{0.5}Co_{0.8}Fe_{0.2}O_{3-{\delta}}$ precursor was synthesized by the polymerized complex method and then calcined at $900^{\circ}C$. As-prepared powder was dispersed in a polymer solution, and extruded as form of hollow fiber through a spinneret. Finallydense $Ba_{0.5}Sr_{0.5}Co_{0.8}Fe_{0.2}O_{3-{\delta}}$ hollow fiber membrane was obtained by sintering for 2 h at $1,080^{\circ}C$ for the application of oxygen separation. In addition, despite a very thin membrane with 0.58 mm, the BSCF hollow fiber membrane possessed a proper mechanical strength of 602.5 MPa.

외경 1.02 mm, 내경 0.437 mm를 갖는 $Ba_{0.5}Sr_{0.5}Co_{0.8}Fe_{0.2}O_{3-{\delta}}$ 중공사를 상전이 방적기술로 제조하였다. 초기 $Ba_{0.5}Sr_{0.5}Co_{0.8}Fe_{0.2}O_{3-{\delta}}$ 선구 분말은 착체중합법을 이용하여 합성하였고, $900^{\circ}C$에서 하소하였다. 합성한 분말을 고분자 용액에 분산시킨 후 이중관형 노즐을 통해 중공사를 사출하였다. 최종적으로 산소분리에 사용 가능한 치밀 $Ba_{0.5}Sr_{0.5}Co_{0.8}Fe_{0.2}O_{3-{\delta}}$ 중공사막을 $1,080^{\circ}C$에서 2 시간 동안 소결하여 얻을 수 있었다. 또한 0.58 mm의 매우 얇은 분리막임에도 불구하고, BSCF 중공사 분리막은 602.5 MPa의 적당한 기계적 강도를 유지하였다.
