Abstract

TiO₂, MgO, Mo, Al₂O₃ and Bi₂O₃ up to a few percentages in quantity were intentionally added to BaZr_0.9Y_0.1O_{3 - δ}. The selected additives do not contribute to any improvement of the sintering behaviour. The lattice parameter of BaZr_0.9Y_0.1O_{3 - δ} for the samples containing additives is smaller than for the pure material. The bulk conductivity also falls drastically with metal addition. For instance, the conductivity of the sample containing TiO₂ is 2.5 orders of magnitude lower than the sample without additive. The grain boundary conductivity is also affected by the presence of metal ions.
