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 ...
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 ...
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 ...
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 ...
Mechanically activated coal ash as refractory bauxite shotcrete microfiller: Thermal interactions mechanism investigation
(Elsevier, 2014)
A growing demand for refractory castables with advanced properties has given rise to a continuous technological evolution and highlighted the necessity for secondary raw materials reapplication even in refractory industry. ...
Ferroelectric nanocomposites of polyvinylidene fluoride/polymethyl methacrylate blend and BaTiO3 particles: Fabrication of β-crystal polymorph rich matrix through mechanical activation of the filler
(AIP Publishing, 2014)
Nanocomposites of polyvinylidene fluoride/polymethyl methacrylate (PVDF/PMMA) blend and mechanically activated barium titanate (BaTiO3) particles were prepared by melt mixing. Modification of filler by means of mechanical ...
Raman Responses in Mechanically Activated BaTiO3
(Hoboken, NJ : John Wiley & Sons, 2014)
The structure and lattice dynamics of mechanically activated BaTiO3 was investigated in this study. Phonon behavior and crystal structure stability of the obtained nanocrystalline BaTiO3 were discussed from the view point ...
Influence of Mechanical Activation on the Constituents of the MgO-Al2O3-SiO2-MoO3 System
(Belgrade : Serbian Ceramic Society, 2014)
Cordierite, 2MgO•2Al2O3•5SiO2 (MAS), is high-temperature ceramic material. Cordierite is commonly used material because of outstanding electrical properties, low temperature expansion coefficient and low dielectric constant. ...
