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 ...
Uticaj mehaničke aktivacije na svojstva MgO-TiO2 elektrokeramike
(Čačak : University of Kragujevac, Faculty of Technical Sciences, 2015)
Intenzivan razvoj elektronike najvećim delom zavisi od razvoja novih materijala, koji se pored strogo određenog sastava odlikuju i tačno određenom raspodelom defekata i primesa. Sa sve rasprostranjenijom primenom tehnike ...
Influence of synthesis parameters and thermal treatment on functional properties of Fe3O4-BaTiO3 multiferroics obtained by mechanical activation
(Belgrade : Serbian Ceramic Society, 2017)
Mechanical activation of a mixture of polycrystalline powders Fe3O4 (50% wt.) and BaTiO3 (50% wt.) was performed in a planetary ball-mill, with different milling times (3 h, 6 h and 12 h). Average crystallite size determined ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Elsevier, 2014)
Ferroelectric barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using as the starting compounds powder of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide ...
Kinetics of Mechanically Activated TiO2-based Oxides Followed by DTA
(Belgrade : Serbian Ceramic Society, 2012)
TiO2-based materials are widely used in production of ceramic capacitors and semiconductors. The conventional method of ceramics synthesis relies on the solid-state reaction between TiO2 and other compounds (BaCO3, BaO, ...
Synthesis of LiFePO4 by mechanical stressing and thermal annealing
(Belgrade : Materials Research Society of Serbia, 2014)
Mechanical activation can be regarded as a multi-step process with changes in the energetic parameters and the amount of accumulated energy of solids in each step. Here we report the influence of mechanochemical processing ...
Structural characterization of mechanically activated MgO-TiO2 system
(Belgrade : Materials Research Society of Serbia, 2011)
Mixtures of MgO-TiO2 powders were mechanically activated in a planetary ball mill for time interval from 0 to 120 minutes. On thus obtained powders, structural investigations have been performed. N2 adsorption method was ...
Assessment of intensive grinding effects on alumina as refractory compound: Acceleration of γ to α phase transformation mechanism
(Elsevier, 2014)
In this study, the feasibility of alumina phase transition enhancement by mechanical activation was conducted. It was showed that the milling environment plays an important role on the physical, chemical and thermal behavior ...
Investigation of thermally induced processes in corundum refractory concretes with addition of fly ash
(Springer Netherlands, 2015)
The effects that the fly ash addition has on the behavior of thermally resistant corundum concrete were discussed. Experimental program implied production of two refractory composites: "referent" concrete from 20 % of ...
The Influence of Mechanical Activation on Sintering Process of BaCO3-SrCO3-TiO2 System
(Belgrade : Serbian Ceramic Society, 2012)
In this article the influence of mechanical activation on sintering process of barium-strontiumtitanate ceramics has been investigated. Both non-activated and mixtures treated in planetary ball mill for 5, 10, 20, 40, 80 ...
