Enhanced stability in CO2 of Ta doped BaCe0.9Y0.1O3-delta electrolyte for intermediate temperature SOFCs
(Elsevier Sci Ltd, Oxford, 2013)
The influence of Ta concentration on the stability of BaCe(0.9-)xTa(x)Y(0.1)O(3-delta) (where x=0.01, 0.03 and 0.05) powders and sintered samples in CO2, their microstructure and electrical properties were investigated. ...
Effect of preparation route on the microstructure and electrical conductivity of co-doped ceria
(Elsevier Sci Ltd, Oxford, 2013)
Dense Ce0.8Sm0.1Gd0.1O2-delta electrolytes were fabricated by sintering of CeO2 solid solutions which were prepared from metal nitrates and NaOH using self propagating room temperature synthesis (SPRT). Three different ...
Chemical stability and electrical properties of Nb doped BaCe0.9Y0.1O3-delta as a high temperature proton conducting electrolyte for IT-SOFC
(Elsevier Sci Ltd, Oxford, 2013)
BaCe0.9-xNbxY0.1O3-delta (where x=0, 0.01, 0.03 and 0.05) powders were synthesized by solid-state reaction to investigate the influence of Nb concentration on chemical stability and electrical properties of the sintered ...
Influence of mechanical activation on sphene based ceramic material synthesis
(Elsevier Sci Ltd, Oxford, 2013)
Sphene (CaTiSiO5), a calcium titanosilicate ceramic has been prepared from a powder mixture of CaCO3, TiO2 and SiO2 using vibromilling for homogenization and activation of precursors. The mechanochemical process initially ...
High-voltage electrophoretic deposition of preferentially oriented films from multiferroic YMn2O5 nanopowders
(Elsevier Sci Ltd, Oxford, 2013)
Processing of the YMn2O5 powder is very challenging, since it decomposes to YMnO3 and Mn3O4 at temperatures close to 1180 degrees C, while samples consolidation commonly demands high temperatures. The main goal of this ...
Effect of La substitution on the structural and electrical properties of BaBi4-xLaxTi4O15
(Elsevier Sci Ltd, Oxford, 2013)
Pure and lanthanum doped barium bismuth titanate BaBi4-xLaxTi4O15 (BBLT, x=0, 0.05, 0.15, 0.30) ceramics were prepared utilizing solid state method. The X-ray diffraction (XRD) data confirmed formation of single-phase ...
Far infrared and micro structural studies of mechanically activated nickel manganite
(Elsevier Sci Ltd, Oxford, 2013)
Nickel manganite powder synthesized by calcination of a stoichiometric mixture of manganese (MnO Aldrich 99.9%) and nickel oxide (NiO Merck, 99.5%) containing 0.5 wt% CoO and Fe2O3, was additionally mechanically activated ...
