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 ...
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 ...
Phase Formation at the Sintering of Sa, Zn, Ti Oxides
(Kiev, 2009)
Complex compounds with oxide phases of Ba, 2n, and 11 are widely used in instrument engineering. It is also important to find such production routes for ceramics, which provide their stable structure and properties. Phase ...
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 ...
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 ...
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 ...
Sintering of mechanically activated Zno-TiO 2 powders
(Springer, 2008)
Zinc oxide and titanium dioxide powders mixed in an equimolar ratio are mechanically activated in a planetary ball mill and sintered under nonisothermal and isothermal conditions. Nonisothermal sintering is studied using ...

Poster presented at the conference Fizika i tehnologija materijala (Physics and Technology of Materials), FITEM '07, Čačak, Serbia, August 6-8, 2007.
Ispitivanje sinterovane cink-kalaj-oksidne keramike fotoakustičnom spektroskopijom
(Beograd : Savez hemijskih inženjera, 2007)
Prahovi ZnO i SnO2 pomešani u molamom odnosu 2:1 mehanički su aktivi- rani u planetamim mlinu sa kuglama u intervalu od 10 do 160 minuta. Do- bijene smeše presovane su i izotermski sinterovane na 1300 °C, dva sata. Uzorci ...
Enhancing Synthesis and Sintering of Zinc Titanate Using Mechanical Activation
(Progress in Advanced Materials and Processes, 2004)
Mechanical activation and sintering are used for obtaining zinc titanate, Zn2TiO4. Starting powder mixtures of ZnO and TiO2, in the molar ratio that is in accordance with the stoichiometry ofzinc titanate Zn2TiO4, were ...
