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 ...
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 ...
Synthesis and characterization of zinc titanate nano-crystal powders obtained by mechanical activation
(Belgrade : International Institute for the Science of Sintering, 2005)
Development of dielectric materials for microwave frequencies is increasing with rapid progress in mobile and satellite communications systems, where zinc titanates have found application due to their semi-conducting and ...
Isothermal sintering of mechanically activated MT ceramics
(Kiev, 2009)
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 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 ...
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 ...
Influence of mechanical activation on BaO-ZnO-TiO2 system
(Belgrade : Institute of Technical Sciences of SASA, 2008)
The influence of mechanical activation on BaO-ZnO-TiO2 sistem was observed. Mixtures of BaO-ZnO-TiO2 were mechanically activated using high-energy planetary ball mill during 0,5, 10, 20, 40 and 80 minutes. XRD analyses ...
The synthesis: Structure relationship in the ZnO-Cr2O3 system
(Belgrade : International Institute for the Science of Sintering, 2004)
In this work the development of the spinel phase in the ZnO-Cr2O3 system was discussed from the viewpoint of the synthesis-structure relationship. The nanostructure evolution in particles obtained either via solution-based ...
Reaction sintering of the 2ZnO-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2007)
Sintering kinetics of the mechanically activated ZnO-TiO2 system was studied. Mixtures of ZnO and TiO2 powders were mechanically activated using a high-energy ball mill for different time intervals from 0 to 300 minutes. ...
Primena Ramanove spektroskopije u proučavanju mehaničke aktivacije BaTiO3
(Beograd : Institut tehničkih nauka SANU, 2006)
U ovom radu su ispitivane strukturne promene BaTiO3 tokom mehaničke aktivacije. Kao početni prah, korišćen je BaTiO3 (Aldrich) prah čistoće 99.9%. Mehanička aktivacija ovog praha izvršena je mlevenjem u visokoenergetskom ...
