The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3
Poster presented at the conference Advanced Ceramics and Application II – Serbian Ceramic Society, Belgrade, September 30 – October 1, 2013
Isothermal sintering of mechanically activated MT ceramics
The aim of this work was to analyze influence of mechanical activation on MgO-TiO2 system. Mixtures of MgO-TiO2 were mechanically activated for 0, 5, 10, 20, 40, 80 and 120 minutes in a planetary ball mill and after that ...
Influence of MoO3 on sintering temperature of mechanically activated MgO-Al2O3-SiO2 system
(Belgrade : Serbian Ceramic Society, 2013)
Cordierite, 2MgO⋅2Al2O3⋅5SiO2, is a very attractive high-temperature ceramic material, due to its outstanding electrical characteristics, such as the low temperature expansion coefficient, low dielectric constant and good ...
Structural investigation of mechanically activated ZnO powder
Abstract Commercially available ZnO powder was mechanically activated in a planetary ball mill. In order to investigate the specific surface area, pore volume and microstructure of non-activated and mechanically activated ...
Simultaneous enhancement of natural sunlight- and artificial UV-driven photocatalytic activity of a mechanically activated ZnO/SnO2 composite
(Royal Society of Chemistry, 2017)
Mechanical milling of commercial ZnO and SnO2 was used to produce a ZnO/SnO2 composite with a high density of surface defects; in particular, zinc interstitials (Zni) and oxygen vacancies (VO). To determine the impact of ...
Structural and electrical properties of ferroelectric poly(vinylidene fluoride) and mechanically activated ZnO nanoparticle composite films
(IOP Publishing, 2018)
The influence of the mechanical activation of ZnO nanoparticle fillers on the structural and electrical properties of the matrix of poly(vinylidenefluoride)-ZnO (PVDF-ZnO) films was investigated. Transmission electron ...
Influence of mechanical activation on synthesis of zinc metatitanate
(Belgrade : International Institute for the Science of Sintering, 2005)
Investigations of a ZnO-TiO2 binary oxide mixture during mechanical treatment were mainly focused on obtaining orthotitanate Zn2TiO4 with a spinel structure. Due to the specific way of energy transfer during mechanical ...
The Morphological Characterization of Mechanically Activated ZnO Powder
(Belgrade : Serbian Ceramic Society, 2014)
The authors investigated the morphological characteristics of mechanically activated ZnO powder. ZnO powder was mechanically activated for 2, 5, 10 and 30 minutes in a planetary ball mill. Mechanical activation introduces ...
Electrical Properties of Sintered Magnesium- titanate Ceramics
(Belgrade : Serbian Ceramic Society, 2012)
Mixtures of MgO and TiO2 were mechanically activated in a planetary ball mill for different time intervals. Thus obtained powders were sintered in a furnace for 2 h at temperature of 1300 °C in air atmosphere. Raman ...
