This paper reports the preparation of the dual layer ceramic hollow fiber membrane that made of alumina and a mixed
ion electron conducting (MIEC) material for simultaneous reaction and separation applications. Alumina hollow fiber
membrane was prepared using the phase inversion process followed by a sintering technique at elevated temperature. The
alumina hollow fiber membrane was used as membrane support onto which a thin and dense layer of lanthanum strontium
cobalt ferrite (LSCF) was deposited. The main objective of this study was to investigate the LSCF coating formulations
used in the deposition of LSCF layer onto alumina substrate membrane. The sintering temperature of thin LSCF layer was
varied to investigate gas-tightness properties of LSCF membrane. A series of characterizations were conducted for both
the support and the LSCF membrane. The result showed that the thin layer membranes with thicknesses ranging from 3
to 20 µm were successfully deposited on the surface of alumina hollow fiber support. The sintering process improved the
gas-tightness properties but the sintering temperature above 1150o
C caused defects on the surface of LSCF membrane.
