Shungite - a Russian mineral: possible application as a microwave absorber
(Belgrade : Materials Research Society of Serbia, 2018)
The paper presents results of investigation of the influence of mechanical activation of shungite, a Russian natural mineral rich in silica and carbon, on its sintering behavior. The mechanical activation of the starting ...
New aspects in processing of hydroxyapatite ceramics
(Belgrade : Serbian Ceramic Society, 2017)
Sintering of hydroxyapatite ceramics has been a challenging topic for decades since the material has good bioactivity, proven biocompatibility, low cost, and high availability. Besides its biomaterial applications, ...
Molecular design of nanoparticles and functional materials by sintering
(Beograd : Tehnološko-metalurški fakultet Univerziteta u Beogradu, 2012)
Nanosized powders present an excellent starting point for the formation of nonporous materials during the sintering process. Narrow particle size distributions and sufficiently small sizes of the precursor powders typically ...
Pseudobrookite TiFe2O5 nanostructured thick films
(Belgrade : Institute of Technical Sciences of SASA, 2015)
TiO2 (anatase) and Fe2O3 (hematite) nanopowders were mixed in the weight ratio 1:1.5 and 1:2 and homogenized in a planetary ball mill for an hour. After that pastes were prepared of the two powder mixtures, organic vehicle ...
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 ...
Pseudobrookite thick films for potential application as low-temperature sensitive material in NO gas sensors
(IEEE, 2017)
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 ...
Discrete temperature values in the sintering process as a BaTiO3-ceramics properties parameter
(Belgrade : International Institute for the Science of Sintering, 2017)
In this paper, we develop the new physical-mathematical time scale approach-model applied to BaTiO3-ceramics. At the beginning, a time scale is defined to be an arbitrary closed subset of the real numbers R, with the ...
Sintering of Zinc-Titanate
(Atlantis Press, 2016)
Sintering kinetics of the mechanically activated ZnO-TiO2 system was studied. Mixtures of ZnO and TiO2 powders were mechanically activated using a high-energy ball mill for different time intervals from 0 to 300 min. Formal ...
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 ...
Influence of mechanical activation on functional properties of barium hexaferrite ceramics
(Elsevier, 2018)
Barium hexaferrite ceramics were prepared using mechanically activated mixtures of iron and barium titanate. The 60:40 mass% Fe:BaTiO3 powder mixtures were mechanically activated for different times (100–240 min) and ...
