Razvoj mikrostrukture i kristalnih faza tokom sinterovanja višefaznih materijala na bazi Zn0 i njihov uticaj na formiranje nelinearnih strujno-naponskih karakteristika
(Belgrade : University of Belgrade, Faculty of Technollogy and Metallurgy, 1993)
Rad predstavlja nastavak dosadašnjih istraživanja iz oblasti višekomponentnih materijala na bazi ZnO - Bi2O3 - MO, koji poseduju veliku nelinearnost strujno-naponske karakteristike. Nelinearno ponašanje sistema, koje se ...
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 ...
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
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 ...
Formation of porous wollastonite-based ceramics after sintering with yeast as the pore-forming agent
(Belgrade : International Institute for the Science of Sintering, 2017)
In this paper, synthesis of porous wollastonite-based ceramics was reported. Ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as starting material. After 20 min of ultrasound treatment, ...
Structural and electrical properties of sintered zinc-titanate ceramics
The aim of this work was an investigation of structural and electrical properties of sintered zinc-titanate ceramics obtained by mechanical activation. Mixtures of ZnO and TiO2 were mechanically activated in a planetary ...
Designing, fabrication and characterization of nanostructured functionally graded HAp/BCP ceramics
Nanostructured calcium phosphate functionally graded materials (FGMs) with simultaneous gradients of density, phase composition, and mechanical properties were fabricated by consecutive uniaxial pressing of stoichiometric ...
Sintering of defect-free functionally graded biomaterials
(Belgrade : Materials Research Society of Serbia, 2011)
Functionally graded materials (FGMs) with a gradient of chemical, electrical, mechanical and/or biological properties are very attractive because of their superior features compared to conventional materials. It is known ...
Full density calcium phosphate bioceramics from nanopowders by sintering
Poster presented at the Adriatic School of Nanoscience – ASON-1, Dubrovnik, Croatia, September 19–23, 2010
Synthesis of barium-zinc-titanate ceramics
(Belgrade : International Institute for the Science of Sintering, 2012)
Mixtures of BaCO3, ZnO and TiO2 powders, with molar ratio of 1:2:4, were mechanically activated for 20, 40 and minutes in a planetary ball mill. The resulting powders were compacted into pellets and isothermally sintered ...
