Transformation of Cs-LTA type of zeolite to pollucite phase using hot pressing method
(Institute for Multidisciplinary Research, University of Belgrade, 2017)
Cesium aluminosilicate phases are of the great interest as possible hosts for Cs immobilization in radioactive waste management. Cs-exchanged form of Na, Ca-LTA type of zeolite (Cs-LTA) was prepared by standard procedure ...
PZT-NICKEL FERRITE AND PZT-COBALT FERRITE COMPARATIVE STUDY: STRUCTURE, DIELECTRIC, FERROELECTRIC AND MAGNETIC PROPERTIES OF COMPOSITE CERAMICS
(Institute for Multidisciplinary Research, University of Belgrade Kneza Višeslava 1, 11000 Belgrade, Serbia, 2017)
Multiferroic (MF) materials with simultaneous magnetic and electric long range order and occasionally, mutual magnetoelectric (ME) coupling, have recently attracted considerable interest. These compounds present opportunities ...
Improved properties of doped BaCe0.9Y0.1O3-δ as a proton conducting electrolyte for IT-SOFC
(Društvo za keramičke materijale Srbije, 2017)
The proton conductivity is an exclusive property of mixed oxides with
perovskite structure and large unit cell volume, such as BaCeO3 or SrCeO3. Doping
with aliovalent cations (Y3+) that replace Ce4+ induces formation ...
B-site doping as a strategy for tailoring BiFeO3 properties
(Društvo za keramičke materijale Srbije, 2017)
Ferroelectric, magnetic and structural properties of BiFe1–xNbxO3 (x = 0.002,
0.005 and 0.01) ceramics were investigated in order to study the influence of B-site
doping of multiferroic BiFeO3. It is known that pure ...
STRUCTURE AND CHARACTERIZATION OF (x)Ni0.7Zn0.3Fe2O4 – (1-x)BaTiO3 COMPOSITES
(Institute for Multidisciplinary Research, University of Belgrade Kneza Višeslava 1, 11000 Belgrade, Serbia, 2017)
Multiferroic composites with formula Ni0.7Zn0.3Fe2O4 - BaTiO3 (x = 0.1, 0.3, 0.5, 0.7, 0.9) were prepared by mixing chemically obtained NZF and BT powders in the planetary mill for 24 h. NiZnFe2O4 (NZF) powder was prepared ...
CORRELATION BETWEEN STRUCTURE AND ELECTRICAL CHARACTERISTICS IN SAMARIUM DOPED BARIUM TITANATE SYSTEMS
(Institute for Multidisciplinary Research, University of Belgrade Kneza Višeslava 1, 11000 Belgrade, Serbia, 2017)
Conventional solid-state method was used to prepare powders of barium titanate (BT) doped with different concentration of Sm. Influence of Sm addition on the structure modification, grain growth inhibition and microstructure ...
INFLUENCE OF DOPING ION VALENCE AND SIZE ON PROPERTIES OF BiFeO3 MATERIALS
(Institute for Multidisciplinary Research, University of Belgrade Kneza Višeslava 1, 11000 Belgrade, Serbia, 2017)
Bismuth ferrite (BiFeO3) is one of the most promising single multiferroic materials, and for sure the most studied one. It expresses specific magnetic and electric properties well above the room temperature. However, the ...
THE OVERVIEW OF BARIUM TITANATE PROPERTIES AND APPLICATION OPPORTUNITIES
(Institute for Multidisciplinary Research, University of Belgrade Kneza Višeslava 1, 11000 Belgrade, Serbia, 2017)
Barium titanate (BT) is a ferroelectric material with a perovskite structure important in the field of electronics. Due to high flexiblity of its crystal lattice it has the capabilty to host ions with different oxidation ...
