Ho2O3 Additive Effects on Microstructure and Dielectrical Properties of BaTiO3 Ceramics
(Belgrade : Serbian Ceramic Society, 2012)
Doped BaTiO3-ceramics is very interesting for its application as resistors with PTCR, multilayer ceramics capacitors, thermal sensors etc. Ho doped BaTiO3 ceramics, with different Ho2O3 content, ranging from 0.01 to 1.0 ...
Up-conversion Luminescence in Ho3+ and Tm3+ co-doped Y2O3 :Yb3+ Fine Powders
(Belgrade : Serbian Ceramic Society, 2012)
Fine yttrium oxide powders doped with Yb3+ and co-doped either with Tm3+ or Ho3+ were synthesized via spray pyrolysis at 900 °C using 0.1 M nitrate precursor. Synthesized powders were additionally thermally treated at 1100 ...

Structural Changes, Dielectric and Ferroelectric Properties of Tribophysically Activated BaTiO3
(Belgrade : Serbian Ceramic Society, 2012)
In order to obtain nanocrystalline material which can be used in MLCC production, the investigations of the influence of BaTiO3 powder tribophysical activation (TPA) on its structural changes, dielectric and ferroelectric ...
Study of Dielectric Behavior and Electrical Properties of Hematite a-Fe2O3 Doped with Zn
(Belgrade : Serbian Ceramic Society, 2012)
The effects of Zn-doping on the dielectric behavior and electrical properties of bulk alpha-Fe2O3 have been studied. X-ray diffraction analysis revealed the presence of two phases in all samples: hematite and spinel ZnFe2O4, ...
Aerosol-assisted Processing of Dopamine-TiO2 Colloidal Solution
(Belgrade : Serbian Ceramic Society, 2012)
Set of colloidal TiO2 nanoparticles solutions (TiO2 NPs) were surface modified with the different quantities of dopamine (DA) and then are used as precursors for the synthesis of DA modified submicronic TiO2 particles ...
Influence of Mechanical Activation on the Constituents of the MgO-Al2O3-SiO2-TiO2 System
(Belgrade : Serbian Ceramic Society, 2012)
Cordierite, 2MgO2Al2O35SiO2, is a very attractive high-temperature ceramic material, due to its outstanding electrical characteristics, such as the low temperature expansion coefficient, low dielectric constant and good ...
