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, ...
Characterization and radionuclides contents of diatomaceous earth from Kolubara mining basin, Serbia
(Univeristy of Belgrade, Faculty of Mining and Geology, Belgrade, Serbia, 2019)
Diatomaceous earth is of sedimentary origin consists mainly of accumulated skeletons formed as a protective covering of the diatoms. Usually, high absorption capacity of diatomaceous earth provides its wide use as heat ...
Composition and natural radionuclides in clay from Kolubara mining basin, Serbia
(Univeristy of Belgrade, Faculty of Mining and Geology, Belgrade, Serbia, 2019)
The mining basin Kolubara lies about 50 km southwest of Belgrade and stretches across the river Kolubara from Lajkovac to its mouth in the Sava River. During coal exploitation a huge amount of clay is deposited ...
Solvothermal synthesis of Ti doped ZnO
(The Serbian Ceramic SocietyVinča Institute of Nuclear Sciences, University of BelgradeInstitute for Multidisciplinary Research, University of BelgradeInstitute of Physics, University of Belgrade, 2011)
Titanium doped zinc oxide powders were synthesized by solvothermal method.
Polycrystalline powders of ZnO with different amounts of Ti -Zn1-xTixO (x=0, 1, 2, 5,
7.5, 10 at%) were obtained from ethanolic solution of zinc ...
Microstructure and functional properties of solution-derived Sr-modified potassium sodium niobate thin films
(Electroceramics XV, June 27-28-29, 2015, Limoges, France, 2015)
Over the past few decades, the potassium sodium niobate, K0.5Na0.5NbO3 (KNN) has drawn a lot of research interests as an environment-friendly lead-free ferroelectric material suitable for production of thin-film electronic ...
Preparation and dielectric properties of CuAlO2 ceramics
(48th International Conference on Microelectronics, Devices and Materials with the Workshop on Ceramic Microsystems, 2012)
Within this work, the focus was on preparation of the delafossite CuAlO2 single phase powder and ceramic with a high density by the solid state synthesis, and on dielectric properties of the as-synthesized ceramic. The ...
FAR INFRARED AND MICROSTRUCTURAL STUDIES OF MECHANICALLY ACTIVATED NICKEL MANGANITE
(Institute for Multidisciplinary Research, University of Belgrade, 2011)
Nickel manganite powder was mechanically activated in a high energy planetary ball
mill for 5-60 min. Then the powders were pressed and sintered for 60 minutes at 9000C,
10500C and 12000C. Morphological changes of nickel ...
