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 ...
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 process influence on microstructure and intergranular impedance of rare-earth modified BaTiO3-ceramics
(Belgrade : International Institute for the Science of Sintering, 2011)
Sintering process is a complex of different synergetic effects during the ceramics materials consolidation. The microstructural level properties control is very important as a stage in advanced materials prognosis. SEM ...
The master sintering curves for BaTi0.975Sn0.025O3/BaTi0.85S n0.15O3 functionally graded materials
The most important aim in the design and processing of functionally graded materials (FGMs) is to produce devices free from any deformation. Smart choices of different combination of graded layers, as well as the heating ...
Humidity sensing potential of Fe2TiO5—pseudobrookite
(Springer US, 2018)
Bulk samples of pseudobrookite with an orthorhombic crystal structure were prepared by sintering a mixture of starting hematite and anatase nano powders in the weight ratio 60:40 at three different sintering temperatures ...
Synthesis of Cordierite-Based Ceramics : monograph
(Belgrade : Academic Mind, 2016)
Advanced ceramic materials include a large number of new materials, which are very different by their nature. These materials are the result of the demands of modern technologies for operation at high temperatures and ...
Electrical properties of barium titanate stannate functionally graded materials
Barium titanate stannate (BTS) functionally graded materials (FGMs) with different tin/titanium concentration gradient were prepared by the powder-stacking method and uniaxially pressing process, followed by sintering. ...
Influence of different pore-forming agents on wollastonite microstructures
(Belgrade : Serbian Ceramic Society, 2016)
In this study, highly porous macro- and micro-cellular wollastonite-based ceramics was synthesized. Ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as starting material. After 20 min ...
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 ...
