Uticaj mehaničke aktivacije na sintezu cink-metatitanata
(Čačak : University of Kragujevac, Faculty of Technical Sciences, Čačak, 2005)
U ovom radu analiziran je uticaj mehaničke aktivacije na sintezu cink-meta titanata (ZnTiO3). Polazeći od toga da mehanička aktivacija utiče na strukturu praha, menjajući je za naknadnu sintezu procesom sinterovanja, mi ...
The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Societa ceramica italianaPolitecnico di Torino, 2019)
Magnesium aluminate, MgAl2O4, and other alumina-based spinels are refractory ceramics with high hardness and resistance to chemical attack while also being possible microwave dielectrics. Pure MgAl2O4 can be optically ...
Dielectric characteristics of polymer nanocomposites based on PVDF and mechanically activated ZnO powder
(Belgrade : Serbian Ceramic Society, 2021)
ZnO powder was mechanically activated for 10 and 30 minutes in a high energy planetary ball mill, and mixed with 2 wt% PVDF solution to obtain nanocomposite films (50 μm) by casting. ZnO powder activated for 10 and 30 ...
The influence of mechanical activation on sintering process of BaCO3-SrCO3-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2012)
In this article the influence of mechanical activation on sintering process of bariumstrontium-titanate ceramics has been investigated. Both non-activated and mixtures treated in a planetary ball mill for 5, 10, 20, 40, ...
Structural analysis of Zn2TiO4 doped with MgO
(Springer, 2009)
The starting mixtures of ZnO, TiO2, and MgO (0, 1.25, and 2.5 wt.%) powders are mechanically activated in a high-energy planetary mill for 15 min and then sintered between 800 and 1100°C for 2 h. The influence of MgO ...
The Influence of Synthesis Parameters and Heat Effect on Magnetic Properties of Powder System FexOy - BaTiO3
(Belgrade : Serbian Ceramic Society, 2015)
Powder mixture of 60 mass % of iron (Fe) and 40 mass % of barium titanate (BaTiO3) has been activated in planetary mill for 100, 120, 150, 180, 210 and 240 min in the air. During the activation the iron powder transits ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Belgrade : Serbian Ceramic Society, 2013)
Ferroelectric ceramic barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using starting powders of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide (TiO2-anatase). ...
Structural characterization of mechanically activated MgO-TiO2 system
(Belgrade : Serbian Ceramic Society, 2013)
In this article the influence of ball miling process on structure of MgO-TiO2 system was investigated. The mixtures of MgO-TiO2 powders were mechanically activated in a planetary ball mill for the time period from 0 to 120 ...
Shungite – a carbon-mineral rock material: Its sinterability and possible applications
(Novi Sad : Faculty of Technology, University of Novi Sad, 2019)
The paper presents results of the influence of mechanical activation of shungite, a carbon-mineral rock material rich in silica and carbon, on its sintering behaviour, and obtaining of pure SiC ceramics. The mechanical ...
Structural, electrical and magnetic properties of mechanically activated manganese and zinc ferrite
(Belgrade : Institute for Multidisciplinary Research of the University of Belgrade, 2017)
Starting hematite (Fe2O3), zinc oxide (ZnO) and manganese carbonate (MnCO3) powders were homogenized in a planetary ball mill in stainless steel bowls with stainless steel balls for 15 min, calcined in air at 1000 C for ...
