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 ...
Study on bi-layered ceramics powders prepared by the mechanochemical synthesis
(Elsevier Science Sa, Lausanne, 2009)
Bi-layered structured ferroelectric materials-bismuth titanate, Bi4Ti3O12 (BIT) and barium-bismuth titanate, BaBi4Ti4O15 (BBT) powders were prepared by homogenization and sintering of mixture of stehiometric quantities of ...
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 ...
Mechanochemically assisted solid-state and citric acid complex syntheses of Cu-doped sodium cobaltite ceramics
(Elsevier Science Sa, Lausanne, 2015)
In the last decade, the sodium cobaltite ceramic became a promising candidate for potential thermoelectric applications, because of its large thermopower and low resistivity. In this work, polycrystalline samples of ...
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 ...
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 ...
Influence of tungsten doping on dielectric, electrical and ferroelectric behavior of BaBi4Ti4O15 ceramics
(Elsevier Science Sa, Lausanne, 2017)
The effect of tungsten (W6+) doping on modification of the structure, dielectric, ferroelectric and electrical properties of BaBi(4)Ti(4-x)WxO(15) (BBTWx, x = 0, 0.03, 0.05 and 0.07) was investigated. The ceramic samples ...
Positive influence of Sb doping on properties of di-phase multiferroics based on barium titanate and nickel ferrite
(Elsevier Science Sa, Lausanne, 2018)
Multiferroic composite materials based on antimony doped barium titanate/nickel ferrite were prepared by a mixing route. In order to obtain fine grained microstructure composite materials, pure constituent phases were ...
Interdependence between structure and electrical characteristics in Sm-doped barium titanate
(Elsevier Science Sa, Lausanne, 2017)
Conventional solid-state method was used to prepare powders of pure and barium titanate (BT) doped with different concentration of samarium. Influence of samarium addition on the structure modification, grain growth ...
