The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Elsevier, 2019)
Magnesium aluminate, MgAl2O4 and other alumina-based spinels are ceramics with high hardness, high melting point and mechanical strenght. Spinels can also be used as dielectrics in microwave applications. The goal of this ...
Effect of consolidation parameters on structural, microstructural and electrical properties of magnesium titanate ceramics
(Elsevier, 2016)
The aim of this study is to explore the influence of the processing route on the structural and physical properties of bulk MgTiO3 ceramics. Commercially available MgO and TiO2 powders were mechanically activated in a ...

(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2014)
Doktorska disertacija se odnosi na kreiranje gustih nanostrukturnih sinterovanih materijala na bazi hidroksiapatita. Dvostepeno sinterovanje je iskorišćeno za dobijanje bifaznog kalcijum fosfata visoke gustine polazeći od ...
Influence of Bi2O3 on microstructure and electrical properties of ZnO-SnO2 ceramics
(Belgrade : International Institute for the Science of Sintering, 2007)
The effects of small amounts (0.5; 1.0 and 1.5 mol. %) of bismuth oxide on the microstructure and electrical properties of ZnO-SnO2 ceramics have been studied. Starting powders of ZnO and SnO2 were mixed in the molar ratio ...
Electronic ceramic structure within the Voronoi cells model and microstructure fractals contacts surfaces new frontier applications
(Belgrade : International Institute for the Science of Sintering, 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 ...
The Fractal Nature Grains Shape Reconstruction on the Way to Microstructure Prognosis
(Belgrade : Serbian Ceramic Society, 2014)
The structure of BaTiO3 based ceramics materials, can be controlled by using different pressing pressures, sintering temperatures and different additive concentrations. In this paper, microstructure properties of Ho2O3 ...
Composition of red mud and/or metakaolin-based modified geopolymers
(Belgrade : Materials Research Society of Serbia, 2017)
There is potential use of red mud for synthesis of inorganic polymeric materials through a geopolymerization process as an alternative in the sectors of construction and building materials. By introducing of inorganic and ...
Microstructure and dielectric properties of BaTiO3 doped with Er2O3, Yb2O3 and Ho 2O3
(Faenza : ISTEC-CNR, 2008)
Doped barium-titanate ceramic is attracting much interest for its application as resistors with a positive temperature coefficient of resistivity (PTCR), multilayer ceramic capacitors (MLCC), thermal sensors etc. In this ...
Densification rate and phase structure changes during sintering of zinc titanate ceramics
(Elsevier, 2009)
Densification rate and phase structure changes during sintering of nanosized ZnTiO3 were studied. Sintering was performed in a dilatometer in two regimes: the first to 900 °C (heating rates 5, 10 and 15 °C/min) and the ...
The Influence of Temperature on Microstructure Contact Surfaces on BaTiO3 –ceramics Doped with Ho2O3
(Belgrade : Serbian Ceramic Society, 2014)
The materials based on BaTiO3 can be controlled using different technological parameters and different additives. We investigate the influence of different temperature levels of sintering (1320°C, 1350°C and 1380°C) on the ...
