Study of Dielectric Behavior and Electrical Properties of Hematite alpha-Fe2O3 Doped with Zn
(Međunarodni Institut za nauku o sinterovanju, Beograd, 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, ...
The Influence of Compaction Pressure on the Density and Electrical Properties of Cordierite-based Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2015)
Due to its characteristics, cordierite, 2MgO center dot 2Al(2)O(3)center dot 5SiO(2), is a high-temperature ceramic material of a great scientific interest. Mechanical activation of the starting mixtures containing 5.00 ...
Influence of Prolonged Sintering Time on Density and Electrical Properties of Isothermally Sintered Cordierite-based Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2013)
Mechanical activation is a commonly used and relatively fast and inexpensive procedure for sample preparation before the sintering process. Cordierite, a stoichiometric mixture of three different oxides (2MgO center dot ...
Fractal Corrections of BaTiO3-ceramic Sintering Parameters
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
Morphology of ceramics grains and pores as well as Brownian character of particle dynamics inside ceramics specimen contributes to better understanding of the sintering process. BaTiO3-ceramics, studied in this paper, has ...
Structural and Electrical Properties of Ti Doped alpha-Fe2O3
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2013)
In this work we have analyzed the effects of Ti doping on structural and electrical properties of alpha-Fe2O3. When the amount of added Ti (5 wt.% TiO2) was within the solubility degree and XRD, SEM and EDS analysis revealed ...
ZnTiO3 Ceramic Nanopowder Microstructure Changes During Compaction
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2013)
ZnTiO3 nanopowder as a constitutive component in compact production was primarily characterised. Scanning electron micrographs of as received powder were recorded. Mercury porosimetry and nitrogen adsorption were also ...
Sintering Process Influence on Microstructure and Intergranular Impedance of Rare-Earth Modified BaTiO3-Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2011)
Sintering process is a complex of different synergetic effects during the ceramics materials consolidation. The microstructural level properties control is very important as a stage in advanced materials prognosis. SEM ...
Electrical Properties and Microstructure Fractal Analysis of Magnesium-Modified Aluminium-Silicate Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2011)
The addition of Mg(2)(NO)(3) and some active additives, composed of Al salts, to the mixtures of kaolinite and bentonite can provide clay compositions which, after sintering at high temperatures, produce very porous ceramics ...
Isothermal kinetics of titanium-oxo-alkoxy clusters formation
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2011)
In this article, the influences of titanium tetraisopropoxide Ti(OR)4 (R = Pri) concentration, molar ratio, h = [H2O]/[Ti(OR)4], and temperature, on the formation kinetics of the titanium-oxo-alkoxy clusters (TOAC), were ...
Sintering of Mechanically Activated Magnesium-titanate and Barium-zinc-titanate Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2011)
In this article the influence of mechanical activation on sintering process of magnesium-titanate and barium-zinc-titanate ceramics has been investigated. Both non-activated and mixtures treated in planetary ball mill for ...
