Analytical modeling of activation procedure applied in α-alumina thermo-mechanical synthesis
(Elsevier, 2015)
The impact of the mechanical processing parameters on the alumina grain-size distribution affiliated characteristics and on the γ to α phase transformation rate was investigated. The moderation in the alumina samples ...
Effect of consolidation parameters on structural, microstructural and electrical properties of magnesium titanate ceramics
(Elsevier, 2016)
The aim of this study is to explore the influence of the processing route on the structural and physical properties of bulk MgTiO3 ceramics. Commercially available MgO and TiO2 powders were mechanically activated in a ...
Optimization of bentonite clay mechano-chemical activation using artificial neural network modeling
(Elsevier, 2017)
The properties of seven montmorillonite-rich bentonites of different geological origin were investigated prior and subsequent to mechano-chemical processing in an ultra-centrifugal mill. The objective of the experiment was ...
Influence of mechanical activation on functional properties of barium hexaferrite ceramics
(Elsevier, 2018)
Barium hexaferrite ceramics were prepared using mechanically activated mixtures of iron and barium titanate. The 60:40 mass% Fe:BaTiO3 powder mixtures were mechanically activated for different times (100–240 min) and ...
Effects of mechanical activation and two-step sintering on the structure and electrical properties of cordierite-based ceramics
(Elsevier, 2016)
The mechanical activation can help reduce production costs and modify cordierite-based materials. In this study, the structure and electrical properties of the mechanically activated MgO-Al2O3-SiO2 system have been analyzed. ...
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 ...
Influence of ageing of milled clay and its composite with TiO2on the heavy metal adsorption characteristics
(Elsevier, 2015)
The aim of the present study was to investigate the effect of ageing of mechanochemically synthesized clay and its TiO2composite on the simultaneous removal of Pb(II), Cd(II), Cu(II) and Zn(II) ions from acidic aqueous ...
Isothermal sintering of barium-zinc-titanate ceramics
(Oxford : Elsevier Sci Ltd., 2011)
Mixtures of BaCO3-ZnO-TiO2 were mechanically activated using high-energy planetary ball mill during 20, 40 and 80 min. As the time of mechanical activation increased, the decrease in particle size was observed. The effect ...
