Improved total conductivity of nanometric samaria-doped ceria powders sintered with molten LiNO3 additive
(Elsevier, Amsterdam, 2009)
Nanometric 20% molar Sm-doped ceria (SDC20) powders were synthesized by co-precipitation in the presence of N, N, N', N' tetramethylethylendiamine (TMEDA). SDC20 powders were sintered using lithium nitrate salt in various ...
Densification rate and phase structure changes during sintering of zinc titanate ceramics
(Elsevier Sci Ltd, Oxford, 2009)
Densification rate and phase structure changes during sintering of nanosized ZnTiO3 were studied. Sintering was performed in a dilatometer in two regimes: the first to 900 degrees C (heating rates 5, 10 and 15 degrees ...
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 ...
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 ...
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 ...
Antimony doping effect on barium titanate structure and electrical properties
(Elsevier Sci Ltd, Oxford, 2011)
Nanopowders of pure and antimony doped barium titanate (BaTiO3-BT) were synthesized by polymeric precursors method based on Pechini process. Obtained powders were pressed and sintered at 1300 degrees C for 8 h. XRD analysis ...
Structural and electrical properties of sintered Fe2O3/TiO2 nanopowder mixtures
(Elsevier Sci Ltd, Oxford, 2014)
Starting nanopowders of TiO2 (anatase 99.7%) and alpha-Fe2O3 (hematite) were mixed in the weight ratios 60:40 and 40:60. Green samples were sintered in the temperature range 750-1250 degrees C in air. Structural, morphological ...
Structural and electrical properties of BaCe(0.9)Ee(0.1)O(2.95) electrolyte for IT-SOFCs
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
BaCe(0.9)Ee(0.1)O(2.95) (BCE) nanopowder was synthesized by citric-nitric autocombustion method. Rietveld refinement analysis showed that unit cell volume was slightly larger compared with the most known BaCe0.9Y0.1O2.95, ...
Influence of mechanochemical activation on the sintering of cordierite ceramics in the presence of Bi2O3 as a functional additive
(Elsevier, Amsterdam, 2012)
Due to its outstanding electrical characteristics, such as the low temperature expansion coefficient, low dielectric constant and good mechanical properties, cordierite, 2MgO center dot 2Al(2)O(3)center dot 5SiO(2), is a ...
Nanostructured Fe2O3/TiO2 thick films: Analysis of structural and electronic properties
(Elsevier Sci Ltd, Oxford, 2015)
Thick films using starting nanopowders of TiO2 (anatase 99.7%) and alpha-Fe2O3 (hematite) mixed in the weight ratios 60:40 and 40:60 for thick film paste were fabricated by screen printing technology on an alumina substrate. ...
