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. ...
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, ...
Pseudobrookite thick films for potential application as low-temperature sensitive material in NO gas sensors
(IEEE Computer Society, 2017)
Pseudobrookite thick films were obtained by screen printing paste composed of a 1: 1.5 molar ratio mixture of starting nanopowders of hematite and anatase, glass frit and organic binder. The films were deposited on alumina ...
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 ...
Properties of MnZn ferrites prepared by powder injection molding technology
(Elsevier Science Bv, Amsterdam, 2010)
In this work, manganese zinc ferrite components were manufactured by powder injection molding-PIM technology. A fine powder consisting of Mn1-xZnxFe2O4 with small addition of hematite alpha-Fe2O3 as used in mass ferrite ...
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 ...
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 ...
Influence of MgO addition on the synthesis and electrical properties of sintered zinc-titanate ceramics
(Elsevier Science Sa, Lausanne, 2009)
Starting mixtures of ZnO, TiO(2) and MgO (0, 1.25 and 2.5 wt.% MgO) powders were mechanically activated for 15 min in a planetary ball mill. The powders obtained were sintered non-isothermally to temperatures between 800 ...
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 ...
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 ...
