The influence of compaction pressure on the density and electrical properties of cordierite-based ceramics
(Belgrade : International Institute for the Science of Sintering, 2015)
Due to its characteristics, cordierite, 2MgO·2Al2O3·5SiO2, is a high-temperature ceramic material of a great scientific interest. Mechanical activation of the starting mixtures containing 5.00 mass% TiO2 was performed in ...
Influence of mechanical activation on the MgO-Al2O3-SiO2 system with TeO2
(Belgrade : Materials Research Society of Serbia, 2016)
Cordierite 2MgO+2Al2O3+5SiO2 is frequently used ceramic material, that is commonly used as a carrier of electrical components due to its low dielectric constant (~ 5), and low temperature thermal expansion coefficient ...
Uticaj mehaničke aktivacije na strukturu i svojstva stroncijum-titanatne keramike
(Универзитет у Београду, Технолошко-металуршки факултет, 2020)
Cilj ove doktorske disertacije je bio da se analizira i sagleda uticaj mehaničke aktivacije nastrukturu i svojstva nedopiranog i dopiranog SrTiO3 praha, kao i uticaj na strukturu i svojstvakeramike dobijene sinterovanjem ...
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 ...
Influence of mechanical activation on electrical properties of barium–zinc–titanate ceramics sintered at 1100°C
(Springer US, 2012)
Starting mixtures of BaCO3, ZnO, and TiO2 powders are mechanically activated in a planetary ball mill for various periods of time. The powders obtained are sintered isothermally at 1100°C for 120 min. Non-isothermal sintering ...
Synthesis and Characterization of Multifferoics 16%(Fe2O3)4%(BaCO3)80%(BaTiO3)
(Belgrade : Serbian Ceramic Society, 2017)
The initial powder (16 % Fe2O3, 4 % BaCO3, 80 % BaTiO3) was mechanically activated in a planetary mill for 20, 80, 120, 160, 200 and 220 minutes in air. Modified Faraday method was used to perform magnetization measurements ...
Electronic Properties of BZT Nano-Ceramic Grades at Low Frequency Region
(Belgrade : Serbian Ceramic Society, 2021)
Barium zirconium titanate ceramics were prepared using solid state reactions of BaCO3, TiO2 and ZrO2 at elevated temperatures. The prepared BZT was mechanically activated in the planetary ball mill from 0-120 min to achieve ...
Mechanical-chemical synthesis Ba0.77Sr0.23TiO3
(Belgrade : International Institute for the Science of Sintering, 2012)
Barium-Strontium-Titanate Ba0.77Sr0.23TiO3 was prepared from starting materials BaCO3, SrCO3 and TiO2 through solid-state reactions. Mixtures of these oxides are mechanically activated in a high-energy planetary ball mill ...
Kinetics of thermally activated processes in cordierite-based ceramics
(Springer, 2019)
Thermally activated processes in cordierite-based ceramics were investigated to determine the effect of the mechanical activation and the addition of TeO2 on kinetic and thermodynamic parameters of these processes. Using ...
Mechanical Activation and Cation Site Disorder in MgAl2O4
(Materials, 2022)
The synthesis and crystallographic site occupancy were investigated for MgAl2O4 with and without mechanical activation of the precursor powders. Heating to 1200 °C or higher resulted in the formation of a single spinel ...
