La0.6Sr0.4AlxFe1−xO3−δ (LSAF) mixed ionic electronic conducting membranes have been sintered, and the substitution of Al for Fe reduced the density of the sintered body including large defect of pore channels. The sintering behavior of the La0.6Sr0.4Al0.1Fe0.9O3−δ samples have been studied under different oxygen partial pressure, PO_2, and a post process of hot isostatic pressing (HIP) has been carried out. The thermal expansion coefficients and the differential expansion ratios measured in air and under reducing atmosphere for these samples were 15.6 × 10−6/K−1 and 0.37%, respectively, and were not affected by the sintering process. The density of the sample sintered in air was 96.5% and the HIP increase the density of the sample up to 99.6%, eliminating the pores. The three point flexural strength of the HIP sample at 25 and 1000°C were 265 and 208 MPa, respectively, and the oxygen permeation rate of the HIP treated membranes with the thickness of 0.5 mm was 8 cc/min/cm2.
