Phase stability and electrochemical analysis of Nb doped BaCe 0.9Y0.1O3-x electrolyte for IT-SOFCs
(Electrochemical Society Inc., 2010)
Barium cerate-based electrolytes containing different amounts of Nb 5+ as a dopant were investigated with the aim of attaining materials with improved chemical stability. BaCe0.9.xNbxY 0.1O3-x (BCYN) powders with different ...
Magnetic properties of doped LaMnO3 ceramics obtained by a polymerizable complex method
(Springer, Dordrecht, 2010)
Substituted lanthanum manganites with the general formula A(1-x) B (x) MnO3 (A = La, B = Ca, SraEuro broken vertical bar) have attracted a lot of attention due to their exceptional electric and magnetic properties. In this ...
Structure study of nanosized La- and Sb-doped BaTiO3
(Elsevier Science Sa, Lausanne, 2010)
Lanthanum and antimony doped barium titanate powders were prepared by polymeric precursors method through Pechini process. Obtained powder was pressed into pellet and sintering was performed at 1300 degrees C for 8 h. The ...
The characterization of the barium titanate ceramic powders prepared by the Pechini type reaction route and mechanically assisted synthesis
(Elsevier Sci Ltd, Oxford, 2010)
BaTiO3 ceramic powders were prepared by a complex method based on the Pechini type reaction route and mechanically assisted synthesis. In both ways BaTiO3 ceramics were sintered after 120 min on 1300 degrees C without ...
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 ...
Sintering and electrical properties of Ce1-xBixO2-delta solid solution
(Elsevier Science Sa, Lausanne, 2014)
Solid solution Ce1-xBixO2-delta nanopowders with the composition of x = 0.1-0.5 were synthesized by using Self Propagating Room Temperature procedure (SPRT). The results obtained by XRPD show that synthesized samples were ...
Studies on structural, morphological and electrical properties of Ce1-xErxO2-delta (x=0.05-0.20) as solid electrolyte for IT - SOFC
(Elsevier Science Sa, Lausanne, 2015)
A series of four different powders ceria doped Ce1-xErxO2-delta (0.05 lt = x lt = 0.20) were synthesized by applying self-propagating reaction at room temperature (SPRT method). SPRT procedure is based on the self-propagating ...
Dielectric and ferroelectric properties of BST ceramics obtained by a hydrothermally assisted complex polymerization method
(Elsevier Sci Ltd, Oxford, 2015)
Ba0.8Sr0.2TiO3 (BST) powder, obtained by a hydrothermal treatment of precursor solution previously prepared by a complex polymerization method (HT-CPM), was uniaxially pressed and sintered at 1280 degrees C for 1-32 h. The ...
Antiferromagnetism and heat capacity of NaCo2-xCuxO4 ceramics
(Elsevier Sci Ltd, Oxford, 2017)
Polycrystalline samples of NaCo2-xCuxO4 (x=0, 0.01, 0.03 and 0.05) were synthesized in two different ways: 1) by a mechanochemically assisted solid-state reaction method (MASSR) and 2) by a citric acid complex method (CAC). ...
Antimony doping effect on barium titanate structure and electrical properties
(Elsevier Sci Ltd, Oxford, 2011)
