Synthesis and dielectric properties of calcium copper titanate (CCTO) based ceramics
(Belgrade : Institute of Technical Sciences of SASA, 2010)
The perovskite CaCu3Ti4O12 (CCTO) powders with various oxide phase impurities were synthesized via citric gel combustion method. Influence of citric acid amount used for gel preparation was examined in order to lower CCTO ...
Synergistic effect of hydroxyapatite nanopowder’s high crystallinity and non-ordered particles’ boundary regions on low-temperature sintering
Poster presented at 14th Annual Conference of the Materials Research Society of Serbia - YUCOMAT 2012, Herceg Novi, Montenegro, September 3–7, 2012
Pseudobrookite thick films for potential application as low-temperature sensitive material in NO gas sensors
Pseudobrookite thick films were obtained by screen printing paste composed of a 1:1.5 molar ratio mixture of starting nanopowders of hematite and anatase, glass frit and organic binder. The films were deposited on alumina ...
Influence of different pore-forming agents on wollastonite microstructures and adsorption capacities
In this study, porous macro- and micro-cellular wollastonite-based ceramics was synthesized. A ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as a starting material. After 20 min of ...
Electrical Properties of Sintered Magnesium-titanate Ceramics
Poster presented at the conference Advanced Ceramics and Application I - Serbian Ceramic Society, Belgrade May 10-11, 2012
Influence of mechanical activation on synthesis and properties of the MgO-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2007)
Materials applied in electronics such as multilayer capacitors are an important field of ceramic materials. Magnesium titanate based dielectric materials are used for producing type-I capacitors. A common way of obtaining ...
Hydroxyapatite nanopowders prepared in the presence of zirconium ions
Hydroxyapatite nanopowders were prepared in the presence of different concentrations of zirconium ions. Such crystallization conditions yielded significantly reduced particle size and increased specific surface area. Cell ...
Sinterovanje i svojstva sinterovanog ZnTiO3
(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2011)
Ultrafini prah cink-metatitanata veličine čestica 40 do 80 nm podvrgnut je prilikom sintetskog dela tretmana uticajima pritiska i temperature korišćenjem procesa presovanja i reakcionog sinterovanja. S obzirom na nestabilnost ...
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 ...
High temperature sintering kinetics of a-Al2o3 powder
(Belgrade : International Institute for the Science of Sintering, 2003)
The sintering kinetics of a-Al2O3 powder is investigated in this paper Commercial a-Al2O3 powdered compacts were sintered close to 95 % of the theoretical density. The characteristic parameters of sintering kinetics were ...
