Phase transformations and thermal effects of mechanically activated BaCO3-TiO2 system
(Taylor & Francis Ltd, Abingdon, 2002)
Phase transformations and thermal effects of BaTiO3 ceramics due to influence of mechanical activation were investigated. Equimolar mixture of BaCO3 and TiO2 powders was activated in high energy vibromill for various ...
Photoacoustic spectroscopy investigation of sintered zinc-tin-oxide ceramics
(Savez hemijskih inženjera, Beograd, 2007)
In this paper the changes that occured in differently activated ZnO-SnO(2) and sintered samples were investigated using photoacoustic spectroscopy. ZnO and SnO(2) powders, mixed in the molar ratio 2:1, were mechanically ...
Effect of Mechanical Activation on the Densification Behavior of MgAl2O4 Spinel
(The Ceramic Society of Japan, 2019)
Magnesium aluminate and other alumina-based spinels attract attention due to their high hardness, high mechanical strength, and low dielectric constant. MgAl2O4 was produced by solid-state reaction between MgO and a-Al2O3 ...
Synthesis and Characterization of Multifferoics 16%(Fe2O3)4%(BaCO3)80%(BaTiO3)
(Belgrade : Serbian Ceramic Society, 2017)
The initial powder (16 % Fe2O3, 4 % BaCO3, 80 % BaTiO3) was mechanically activated in a planetary mill for 20, 80, 120, 160, 200 and 220 minutes in air. Modified Faraday method was used to perform magnetization measurements ...
Influence of mechanical activation on MgO-TiO2 system
(2008)
Poster presented at the 10th Conference of the Materials Research Society of Serbia - YUCOMAT 2008, Herceg Novi, Montenegro, September 8-12, 2008
Influence of mechanical activation on the MgO-Al2O3-SiO2 system with TeO2
(Belgrade : Materials Research Society of Serbia, 2016)
Cordierite 2MgO+2Al2O3+5SiO2 is frequently used ceramic material, that is commonly used as a carrier of electrical components due to its low dielectric constant (~ 5), and low temperature thermal expansion coefficient ...
Influence of mechanical activation on mechanical properties of PVDF-nanoparticle composites
(Belgrade : Serbian Ceramic Society, 2016)
The influence of mechanically activated fillers (ZnO, BaTiO3 and SrTiO3 ultra-fine powders) on mechanical properties of poly(vinylidene) fluoride (PVDF) and oxide nanoparticle composite was investigated using molecular ...
Influence of mechanochemical activation on sintering of cordierite ceramics with the presence of Bi2O3 as a functional additive
(Belgrade : Materials Research Society of Serbia, 2011)
According to its exceptional electrical characteristics, such as low temperature expansion coefficient, low dielectric constant and good mechanical properties, cordierite, 2MgO⋅2Al2O3⋅5SiO2, represents very attractive ...
The Influence of Mechanical Activation on Sintering Process of BaCO3-SrCO3-TiO2 System
(Belgrade : Serbian Ceramic Society, 2012)
In this article the influence of mechanical activation on sintering process of barium-strontiumtitanate ceramics has been investigated. Both non-activated and mixtures treated in planetary ball mill for 5, 10, 20, 40, 80 ...
Compaction pressure's influence on density and electrical properties of sintered cordierite-based ceramics
(Belgrade : Materials Research Society of Serbia; Institute of Technical Sciences of SASA; Vinča Institute of Nuclear Sciences, University of Belgrade, 2012)
Mechanical activation is widely used for sample preparation before the sintering process. However, the influence of pressure, which is used for compaction, has not been completely investigated. Cordierite, 2MgO_2Al2O3_5SiO2, ...
