Dielectric characteristics of polymer nanocomposites based on PVDF and mechanically activated ZnO powder
(Belgrade : Serbian Ceramic Society, 2021)
ZnO powder was mechanically activated for 10 and 30 minutes in a high energy planetary ball mill, and mixed with 2 wt% PVDF solution to obtain nanocomposite films (50 μm) by casting. ZnO powder activated for 10 and 30 ...
The influence of mechanical activation on microstructure and dielectric properties of SrTiO3 ceramics
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2021)
In recent years, a lot of interest has been shown in obtaining materials with predetermined properties. The aim is to establish a functional dependence between the synthesis parameters, structural characteristics, and ...
Диелектрична керамика баријум‑стронцијум‑титаната / Dielectric Barium Strontium Titanate Ceramics

Microstructural and optical properties of MgAl2O4 Spinel: Effect of Mechanical Activation, Yttrium and Graphene addition
(Belgrade : Serbian Ceramic Society, 2021)
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 α-Al2O3 ...
Microstructural and Optical Properties of MgAl2O4 Spinel: Effects of Mechanical Activation, Y2O3 and Graphene Additions
(Basel : MDPI AG, 2021)
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 a solid-state reaction between MgO and α-Al2O3 ...
Electrical properties of isothermally sintered cordierite-based ceramics as function of sintering and activation time / Električna svojstva izotermski sinterovane keramike na bazi kordierita kao funkcija vremena sinterovanja i aktivacije
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2021)
The mechanical activation of the starting mixtures of cordierite (2MgO*2Al2O3*5SiO2) with 5.00 mass % TiO2 was performed in a high energy ball mill during 10-80 min. The applied compaction pressure before the sintering ...
