Preparation and Characteristics of Ceramic Hollow Fiber Membranes for Oxygen Permeation
Source abstract
Abstract
A mixed oxide-electron conducting ceramic, La0.6Sr0.4Co0.2Fe0.8O3-α (LSCF) hollow fiber membrane was prepared by the phase inversion technique. The ceramic hollow fibre membranes have the asymmetric structure with spongy and dense layers. The dense hollow fibre membranes without defects can be obtained after sintering at 1300 ℃ for 4h. The crystalline grain of LSCF in the membranes becomes larger after sintering at high temperatures, however the per-ovskite crystalline structure doesn't change. The permeability of LSCF hollow fiber membrane is higher than that of the common tube membrane.
