A new family of MIEC compounds resulting from the electrolyte BaIn0.3Ti0.7O2.85 (BIT07) was developed by coupled substitution of titanium by iron and barium by lanthanum. Total conductivity increases significantly with iron and lanthanum content. BaIn0.3Ti0.7O2.85 yields a total conductivity in air of 10(-2) S cm(-1) at 700 degrees C whereas that of Bi0.7La0.3In0.3Ti0.1Fe0.6O3-delta (BLITFe06) is 3 S cm(-1). Doped compounds are p-type conductors. In reducing atmosphere the electrical conductivity decreases drastically to sigma = 2 x 10(-2) S cm(-1) for the best value, which is not sufficient for a use as MIEC anode. Nevertheless. Ni/BLITFe06 cermets seem to be good candidates as SOFC anodes. The total conductivity of Ni/BLITFe cermets is higher than that of 18.7 vol.% Ni/BIT07 (sigma(700 degrees C) approximate to 10(2) S cm(-1)), even for a lower Ni content (16.1 vol.% Ni/BLITFe (sigma(770 degrees C) approximate to 200 S cm(-1)). The percolation threshold moves towards the small quantities of nickel (from 15.7 vol.% to 10 vol.%). Ni/BLITFe06 cermets, compared with Ni/BIT07, show a better electrochemical behaviour towards fuel oxidation. (C) 2011 Elsevier B.V. All rights reserved.
