The impedance analysis of sintered MgTiO3 ceramics
(Elsevier, 2017)
In the present study the effect of preparation conditions on microstructure and electrical properties of MgTiO3 ceramics was investigated. Mixture of MgO and TiO2 powders was subjected to mechanical activation for different ...
Intrinsic resistivity of sintered Nickel Manganite vs. powder activation time and density
(Belgrade : International Institute for the Science of Sintering, 2008)
In this work the DC resistivity of sintered nickel manganite NiMn2O4 (NTC thermistor material) was studied as a function of additional powder activation time in a planetary ball mill (0, 5, 15, 30, 45 and 60 min). The ...
The influence of mechanical activation on microstructure and dielectric properties of SrTiO3 ceramics
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2021)
In recent years, a lot of interest has been shown in obtaining materials with predetermined properties. The aim is to establish a functional dependence between the synthesis parameters, structural characteristics, and ...
Диелектрична керамика баријум‑стронцијум‑титаната / Dielectric Barium Strontium Titanate Ceramics
(Београд : Задужбина Андрејевић, 2021)
С обзиром на то да развој савремене технике није могућ без нових ма‑ теријала, што је објективно последица достигнућа у области науке о материјалима, аутор се у овој монографији бави керамичким материјали‑ ма који већ дуги ...
Synthesis of BaTiO3 from a mechanically activated BaCO 3-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2008)
In this article the solid state reaction of BaTiO3 formation from a mechanically activated BaCO3-TiO2 system has been investigated. An equimolar mixture of BaCO3 and TiO2 powders was activated in a planetary ball mill in ...
Microstructural and optical properties of MgAl2O4 Spinel: Effect of Mechanical Activation, Yttrium and Graphene addition
(Belgrade : Serbian Ceramic Society, 2021)
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 α-Al2O3 ...
Investigation of zinc stannate synthesis using photoacoustic spectroscopy
(Belgrade : International Institute for the Science of Sintering, 2007)
Mixtures of ZnO and SnO2 powders, with molar ratio of 2:1, were mechanically activated for 40, 80 and 160 minutes in a planetary ball mill. The resulting powders were compacted into pellets and non-isothermally sintered ...
Ferroelectric nanocomposites of polyvinylidene fluoride/polymethyl methacrylate blend and BaTiO3 particles: Fabrication of β-crystal polymorph rich matrix through mechanical activation of the filler
(AIP Publishing, 2014)
Nanocomposites of polyvinylidene fluoride/polymethyl methacrylate (PVDF/PMMA) blend and mechanically activated barium titanate (BaTiO3) particles were prepared by melt mixing. Modification of filler by means of mechanical ...
Raman Responses in Mechanically Activated BaTiO3
(Hoboken, NJ : John Wiley & Sons, 2014)
The structure and lattice dynamics of mechanically activated BaTiO3 was investigated in this study. Phonon behavior and crystal structure stability of the obtained nanocrystalline BaTiO3 were discussed from the view point ...
