Statistical Analysis of 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 ...
Influence of nitrogen and air atmosphere during thermal treatment on micro and nano sized powders and sintered TiO2 specimens
(Belgrade : International Institute for the Science of Sintering, 2014)
The influence of air and nitrogen atmosphere during heating on TiO2 nano and micro sized powders as well as sintered polycrystalline specimens was analyzed. Sintering of TiO2 nano and micro powders in air atmosphere was ...
Mechanical activation as sintering pre-treatment of talc for steatite ceramics
(Belgrade : Interenational Institute for the Science of Sintering, 2014)
The effect of vibratory mill induced mechanical activation on the change of the particle size, crystallinity and the phase transformations of the minerals present in the activated material, was studied with the purpose of ...
Properties of Magnesium Titanate Ceramic Obtained by Two Stage Sintering
(Belgrade : Serbian Ceramic Society, 2014)
The aim of this paper was investigation of structural and electrical properties of magnesium titanate ceramic obtained mechanochemically and subjected to two stage sintering process. Mixtures of MgO and TiO2 were treated ...

(2014)
Poster presented at the III Serbian Ceramic Society Conference, 29th September - 1st October, Belgrade, 2014
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Elsevier, 2014)
Ferroelectric barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using as the starting compounds powder of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide ...
Structural and electrical properties of sintered Fe2O3/TiO2 nanopowder mixtures
(Elsevier, 2014)
Starting nanopowders of TiO2 (anatase 99.7%) and α-Fe2O3 (hematite) were mixed in the weight ratios 60:40 and 40:60. Green samples were sintered in the temperature range 750–1250 °C in air. Structural, morphological and ...
Assessment of intensive grinding effects on alumina as refractory compound: Acceleration of γ to α phase transformation mechanism
(Elsevier, 2014)
In this study, the feasibility of alumina phase transition enhancement by mechanical activation was conducted. It was showed that the milling environment plays an important role on the physical, chemical and thermal behavior ...
Microstructure changes caused by thermal etching of sintered ZnTiO3
(2014)
Polishing and thermal etching was performed on ZnTiO3sintered ceramic. Two set of specimens were recorded, on higher 1200oC/1100oC sintered/etched, and lower 900oC/800oC sintered/etched. Phase composition, crystallite sizes ...
BaTiO3 – ceramics and Fractal Microstructure Analyses
(Belgrade : Serbian Ceramic Society, 2014)
Ceramics grain structure is difficult to describe by using traditional analytical methods based on Euclidean geometry. Using the fractal geometric/analytic methods instead, the new approach is offered in this paper. There ...
