Modified glycine nitrate procedure synthesis and properties of nanostructured Ca1-xGdxMnO3 (x=0.05; 0.1; 0.15; 0.2)
(Belgrade : Serbian Ceramic Society, 2021)
Nanocrystalline manganites Ca1-xGdxMnO3(x=0.05, 0.1, 0.15, 0.2) were synthesized by a modified glycine-nitrate procedure. The subsequent studies were focused on the structural, microstructural and magnetic changes of the ...
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 ...
Structural And Functional Investigation Of Fe/Pb/Zr-co-doped Barium Titanate Ceramics: From Theory To The Experiment
(Belgrade : Serbian Ceramic Society, 2021)
Mixtures of high purity powders of 50 mass% Fe, 4 mass% Pb, 3 mass% Zr and 43 mass% BaTiO3 were activated in a rotary ball mill for durations ranging from 30 min to 300 min; samples were then sintered in the air atmosphere ...
Dilatometric study of the ZnTiO3 phase transition kinetic influenced by nano powder sintering
(Belgrade : Serbian Ceramic Society, 2021)
Sintering is often accompanied with phase transition. Phase transition kinetic is thushard to deconvolute due to the superposition of the sintering and phase transition dimensionalchange phenomena. Metastabile perovskite ...
Preparation and characterization of ZrB2-TiB2 based composites for hypersonic systems
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2021)
ZrB2 ceramics are considered potential materials for hypersonic systems in view of the melting point exceeding 3000 °C and excellent ablation resistance. Second phases, including SiC or CrB2, further improve the oxidation ...
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 ...
