The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Societa ceramica italianaPolitecnico di Torino, 2019)
Magnesium aluminate, MgAl2O4, and other alumina-based spinels are refractory ceramics with high hardness and resistance to chemical attack while also being possible microwave dielectrics. Pure MgAl2O4 can be optically ...
The Influence of Synthesis Parameters and Heat Effect on Magnetic Properties of Powder System FexOy - BaTiO3
(Belgrade : Serbian Ceramic Society, 2015)
Powder mixture of 60 mass % of iron (Fe) and 40 mass % of barium titanate (BaTiO3) has been activated in planetary mill for 100, 120, 150, 180, 210 and 240 min in the air. During the activation the iron powder transits ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Belgrade : Serbian Ceramic Society, 2013)
Ferroelectric ceramic barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using starting powders of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide (TiO2-anatase). ...
Structural characterization of mechanically activated MgO-TiO2 system
(Belgrade : Serbian Ceramic Society, 2013)
In this article the influence of ball miling process on structure of MgO-TiO2 system was investigated. The mixtures of MgO-TiO2 powders were mechanically activated in a planetary ball mill for the time period from 0 to 120 ...
Structural, electrical and magnetic properties of mechanically activated manganese and zinc ferrite
(Belgrade : Institute for Multidisciplinary Research of the University of Belgrade, 2017)
Starting hematite (Fe2O3), zinc oxide (ZnO) and manganese carbonate (MnCO3) powders were homogenized in a planetary ball mill in stainless steel bowls with stainless steel balls for 15 min, calcined in air at 1000 C for ...
Characterization of mechanically activated ZnO powder
(Belgrade : Serbian Ceramic Society, 2013)
Materials based on ZnO structure have more frequently application as fillers in polymer ceramics nanocompozites. Performances of these materials depends on fillers morphology, surfaces texture and particles size. According ...
Dilatometric Analysis of Mechanically Activated SrTiO3 Powder
(Belgrade : Serbian Ceramic Society, 2013)
Strontium-titanate powder was mechanically activated in a planetary ball mill for 0, 5, 10, 30, 60, 90 and 120 minutes. Non-isothermal sintering of non-activated and activated SrTiO3 powder samples in the temperature ...
Effect of Mechanical Activation on the Densification Behavior of MgAl2O4 Spinel
(The Ceramic Society of Japan, 2019)
Magnesium aluminate and other alumina-based spinels attract attention due to their high hardness, high mechanical strength, and low dielectric constant. MgAl2O4 was produced by solid-state reaction between MgO and a-Al2O3 ...
The effect of Hot Isostatic Pressing on the MT sample densities
(Belgrade : Serbian Ceramic Society, 2015)
Mechanically activated powders (0, 10, 40, 80 and 160 minutes) were formed by isostatic pressure 300 MPa to cylindrical green bodies (φ 12 mm). First set of samples was sintered at 1300°C for 30 min in air (heating rate ...
