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 ...
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 ...
Changes of Structural, Optical and Electrical Properties of Nickel-Manganite Ceramics Induced by Additional Mechanical Activation
(2007)
Poster presented at the 10th International Conference and Exhibition of the European Ceramic Society, Berlin, June 17-21, 2007
Electrical Properties of Sintered Magnesium- titanate Ceramics
(Belgrade : Serbian Ceramic Society, 2012)
Mixtures of MgO and TiO2 were mechanically activated in a planetary ball mill for different time intervals. Thus obtained powders were sintered in a furnace for 2 h at temperature of 1300 °C in air atmosphere. Raman ...
Primena Ramanove spektroskopije u proučavanju mehaničke aktivacije BaTiO3
(Beograd : Institut tehničkih nauka SANU, 2006)
U ovom radu su ispitivane strukturne promene BaTiO3 tokom mehaničke aktivacije. Kao početni prah, korišćen je BaTiO3 (Aldrich) prah čistoće 99.9%. Mehanička aktivacija ovog praha izvršena je mlevenjem u visokoenergetskom ...
Influence of Mechanical Activation on Electrical Properties of Ceramic Materials in VHF Band
(Belgrade : ETRANBelgrade : Academic Mind, 2019)
Mechanical activation is commonly used as a pre-sintering process in order to enhance the reactivity of materials, reduce the particle size, increase diffusion rates, accelerate the reaction, and lower the sintering ...
Microstructure development and Raman responses of mechanically activated Fe/BaTiO3
(Belgrade : Serbian Ceramic Society, 2015)
The structure and lattice dynamics of mechanically activated nanocrystalline Fe/BaTiO3 is investigated in this work. The powder mixture of 60%Fe and 40% BaTiO3 was mechanically activated up to 240 min in 500 cm3 zirconium ...
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 ...
