    • Surface reactivity and cation non-stoichiometry in BaZr1-xYxO3-δ (x=0-0.2) exposed to CO2 at elevated temperature 

      Sazinas, Rokas; Sunding, Martin Fleissner; Thøgersen, Annett; Sakaguchi, Isao; Norby, Truls Eivind; Grande, Tor; Polfus, Jonathan M. (Journal article; Peer reviewed, 2019)
      The reactivity of BaZr1−xYxO3−δ (x = 0–0.2) ceramics under 1 atm CO2 at 650 °C for up to 1000 h was investigated in order to elucidate possible degradation processes occurring when the material is applied as a proton-conducting ...

    • Tracer diffusion of 96Zr and 134Ba in polycrystalline BaZrO3 

      Sazinas, Rokas; Sakaguchi, Isao; Hasle, Ida Margrete; Polfus, Jonathan M.; Haugsrud, Reidar; Einarsrud, Mari-Ann; Grande, Tor (Journal article; Peer reviewed, 2017)
      Cation tracer diffusion in polycrystalline cubic BaZrO3 perovskites was studied using the stable isotopes 134Ba and 96Zr in air at 1015–1200 and 1300–1500 °C, respectively. Thin films of 134BaO and 96ZrO2 were deposited ...
