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 ...
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 ...
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 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 ...
Dielectric and relaxor behavior of BaBi4Ti4O15 ceramics
(Elsevier Science Sa, Lausanne, 2010)
Barium bismuth titanate BaBi4Ti4O15 (BBiT) ceramics have been prepared using non-conventional solid-state reaction route based on mechanochemical synthesis during intensive milling. The X-ray diffraction method was used ...
Far infrared properties of PbTe doped with cerium
(Elsevier Science Sa, Lausanne, 2007)
Single crystal samples of lead telluride doped with cerium were made using the Bridgman method. Far infrared reflectivity spectra in the temperature range from 10 to 300K are presented. The experimental data were numerically ...
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 ...
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 ...
Influence of the indium concentration on microstructural and electrical properties of proton conducting NiO-BaCe0.9-xInxY0.1O3-delta cermet anodes for IT-SOFC application
(Elsevier Science Sa, Lausanne, 2013)
Optimization of the major properties of anodes based on proton conductors, such as microstructure, conductivity and chemical stability, is yet to be achieved. In this study we investigated the influence of indium on the ...
Magnetic properties of NiMn2O4-delta (nickel manganite): Multiple magnetic phase transitions and exchange bias effect
(Elsevier Science Sa, Lausanne, 2014)
We present magnetic properties of NiMn2O4-delta (nickel manganite) which was synthesized by complex polymerization synthesis method followed by successive heat treatment and final calcinations in air at 1200 degrees C. The ...
