Surface analysis of bismuth titanate by Auger and X-ray photoelectron spectroscopy
(Elsevier, 2009)
The Auger and XPS technique has been used for investigation in the surface of bismuth titanate (Bi4Ti3O12) (BIT) ceramics obtained by reactive sintering from Bi2O3 and TiO2 oxides. All peaks characteristic for bismuth, ...
Preparation and characterization of bismuth germanium oxide (BGO) polymer composites
(Elsevier, 2017)
Bismuth germanium oxide Bi12GeO20 (BGO) has very interesting electrical, optical and magnetic properties. In order to make devices based on this material more flexible, its powder was used for preparing polymer composites. ...
Kinetics of hydrogen absorption in Zr-based alloys
(Elsevier, 2013)
The kinetics of hydrogen absorption in Zr-based alloys Zr–2.5Nb, Zr–10Nb, Zr–2.5Nb–3Ta and Zr–10Nb–12Ta have been investigated in the temperature range 673–973 K at 1 bar hydrogen pressure. The improvement in hydrogen ...
Optical properties of PbTe and PbSnTe doped with Cr
(Elsevier, 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 Pb0.9Sn0.1Te doped with 0.4 at.%, ...
Influence of MgO addition on the synthesis and electrical properties of sintered zinc-titanate ceramics
(Elsevier, 2009)
Starting mixtures of ZnO, TiO2 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 and ...
The impedance analysis of sintered MgTiO3 ceramics
(Elsevier, 2017)
In the present study the effect of preparation conditions on microstructure and electrical properties of MgTiO3 ceramics was investigated. Mixture of MgO and TiO2 powders was subjected to mechanical activation for different ...

Insertion of lithium ion in anatase TiO2 nanotube arrays of different morphology
(Elsevier, 2017)
Anatase TiO2 nanotube arrays of different morphology were prepared by a two-step process: anodic oxidation at voltages 20–60 V and subsequent annealing at 400 °C. By amplifying anodization voltage the inner diameter of ...
