title = "Studies on the perovskite-based La4Srn-4TinO3n+2.",
abstract = "Perovskite titanates with nominal stoichiometry ABO(3+delta) are frequently reported in SOFC literature as having O-3 stoichiometry. Such phases often exhibit quite interesting properties, but are not stoichiometric and the structural characterisation is usually not rigorous. Here we demonstrate how oxygen excess can be incorporated in a titanate perovskite-based lattice as crystallographic oxygen shears giving rise to the homologous series La4Srn-4TinO3n+2. The layered structure is lost for the n=12 member (La4Sr8Ti12O38-delta), although the oxygen excess is accommodated within the perovskite framework in randomly distributed short-range linear defects. Ibis compound was studied as potential fuel electrode due to its high total conductivity and stability in the most reducing conditions.",
