Influence of mechanical activation on structural and electrical properties of sintered MgTiO3 ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2009)
The aim of this work was to analyze the influence of mechanical activation on the MgCO3-TiO2 system. Mixtures of MgCO3-TiO2 were mechanically activated for 15, 30, 60 and 120 minutes in a planetary ball mill and after that ...
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 ...
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 ...

(Međunarodni Institut za nauku o sinterovanju, Beograd, 2013)
In this study, in order to establish grain shapes of sintered ceramics, new approach on correlation between microstructure and doped BaTiO3 -ceramics properties based, on Voronoi model and mathematical statistics calculations ...
Intergranular Area Microalloyed Aluminium-silicate Ceramics Fractal Analysis
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2013)
Porous aluminium-silicate ceramics, modified by alloying with magnesium and microalloying with alluminium belongs to a group of advanced multifunctional ceramics materials. This multiphase solid-solid system has predominantly ...
Enthalpy-entropy Compensation for n-hexane Adsorption on Y Zeolite Containing Transition Metal Cations
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2015)
In this work, the values of entropy changes related to n-hexane adsorption onto cation exchanged Y zeolite were calculated from differential heats. Various transition metal cations (Co2+, Ni2+, Zn2+ and Cd2+) were introduced ...
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 ...
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 ...
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 ...
