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 ...
Optical properties of PbTe and PbSnTe doped with Cr
(Elsevier Science Sa, Lausanne, 2009)
Single crystal samples of PbTe and PbSnTe doped with Cr were made using the Bridgman technique. Far infrared diagrams of PbTe samples doped with 0.4 at.%, 0.8 at.% and 1 at.% Cr and also of Pb(0.9)Sn(0.1)Te doped with 0.4 ...
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 ...
Influence of the ratio between Ni and BaCe0 9Y0 1O3-delta on microstructural and electrical properties of proton conducting Ni-BaCe0 Y-9(0) O-1(3-delta) anodes
(Elsevier Science Sa, Lausanne, 2011)
Cermet anode substrates Ni-BaCe0 9Y0 1O3-delta (Ni-BCY10) with varied ratios between Ni and BCY10 were prepared BCY10 powders were prepared by the citrate-nitrate auto-combustion method and anode substrates were prepared ...
Far infrared study of impurity local modes in palladium-doped PbTe and PbSnTe
(Elsevier Science Sa, Lausanne, 2009)
PbTe and Pb0.85Sn0.15Te single crystals. doped with Pd, were grown using the Bridgman method. Far infrared spectra were measured in the temperature range between 10 K and 300 K. The experimental spectra were numerically ...
Far infrared reflectivity spectra of lead-telluride doped with Ytterbium
(Elsevier Science Sa, Lausanne, 2008)
Single crystal samples of lead-telluride doped with Ytterbium were made using the Bridgman method. Far infrared reflectivity spectra in the temperature range from 10 to 300 K were measured. Analysis of the experimental ...
Mechanochemical synthesis of yttrium manganite
(Elsevier Science Sa, Lausanne, 2013)
Yttrium manganite (YMnO3) is a multiferroic material, which means that it exhibits both ferromagnetic and ferroelectric properties, so making it interesting for a variety of technological applications. In this work, ...
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 ...
Stability, characterization and functionality of proton conducting NiO-BaCe0.85-xNbxY0.15O3-delta cermet anodes for IT-SOFC application
(Elsevier Science Sa, Lausanne, 2014)
There are many of properties of anodes based on proton conductors, like microstructure, conductivity and chemical stability, which should be optimized. In this work we were dealing with the influence of niobium on the ...
Improved electrical properties of Nb doped BaCe0.9Y0.1O2.95 electrolyte for intermediate temperature SOFCs obtained by autocombustion method
(Elsevier Science Sa, Lausanne, 2014)
Nb doped BaCe0.9Y0.1O2.95 (BCY) powders were synthesized by both solid state reaction (SSR) and autocombustion reaction (ACR) method to investigate how different synthesis routes influence the properties of the powders and ...
