| 520 | _ | _ | |a Semi-conducting SrTi0.6Fe0.4O(3-delta) in the form of porous thick films might be of interest as a novel material for resistive hydrocarbon sensor applications. As the underlying gas-sensing mechanism is still a matter of question, thermogravimetric analysis was performed on high-density (>= 99%) SrTi0.6Fe0.4O(3-delta) ceramic specimens in order to investigate whether bulk properties are affected by the catalytic oxidation of propane at the material surface. At temperatures 250-400 degrees C, bulk oxygen content was found to significantly decrease upon exposure to traces of propane (0-3000 ppm) in a background of 20% O-2/80% Ar. Lattice oxygen is sufficiently mobile in this compound so that reducing surface reactions are followed by a bulk redox reaction even at low or moderate temperatures. Concomitant changes in the electrical resistance of dense ceramics are consistent with this picture. The hydrocarbon sensitivity of SrTi0.6Fe0.40O(3-delta) artifacts seems thus to a large extent to be correlated to modifications in the bulk defect chemistry of the material. (c) 2006 Elsevier Ltd.
