Sol-gel Synthesis of Anatase Nanopowders for Efficient Photocatalytic Degradation of Herbicide Clomazone in Aqueous Media
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
TiO2 nanopowders were produced by sol-gel technique using TiCl4 as a starting material. For the preparation of crystalline anatase with developed surface area, this aqueous solution has been mixed with 0.05 M or 0.07 M ...
Characterization of Sedimentary Minerals from Kolubara Mining Basin, Serbia, with the Determination of Natural Radioactivity
(International Institute for the Science of Sintering, 2022)
Diatomite (diatomaceous earth) and clay minerals deposits from the mining basin Kolubara, Serbia, are natural materials with high economic potential in many fields. As received and treated materials, diatomite and clay ...
Study of Barium Bismuth Titanate Prepared by Mechanochemical Synthesis
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2009)
Barium-bismuth titanate, BaBi4Ti4O15 (BBT), a member of Aurivillius bismuth-based layer-structure perovskites, was prepared from stoichiometric amounts of barium titanate and bismuth titanate obtained via mechanochemical ...
Reheating of Zinc-titanate Sintered Specimens
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2015)
The scope of this work was observing dimensional and heat transfer changes in ZnTiO3 samples during heating in nitrogen and air atmosphere. Interactions of bulk specimens with gaseous surrounding induce microstructure ...

Electrical Characterization and Impedance Response of Lanthanum Doped Barium Titanate Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2008)
The dielectric permittivity and dissipation factor of La-doped and undoped BaTiO3 were investigated as a function of frequency and temperature. The impedance response was used to study the electrical properties of La-doped ...
History and Challenges of Barium Titanate: Part II
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2008)
Barium titanate is the first ferroelectric ceramics and a good candidate for a variety of applications due to its excellent dielectric, ferroelectric and piezoelectric properties,. Barium titanate is a member of a large ...
ZnTiO3 Ceramic Nanopowder Microstructure Changes During Compaction
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2013)
ZnTiO3 nanopowder as a constitutive component in compact production was primarily characterised. Scanning electron micrographs of as received powder were recorded. Mercury porosimetry and nitrogen adsorption were also ...
Modification of the structural and optical properties of commercial ZnO powder by mechanical activation
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Mechanical activation was used as a method for modification of the structural and optical properties of commercial ZnO powder. For this purpose zinc oxide powder was mechanically treated by grinding in a high-energy ...
Influence of Bi2O3 on microstructure and electrical properties of ZnO-SnO2 ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
The effects of small amounts (0.5; 1.0 and 1.5 mol. %) of bismuth oxide on the microstructure and electrical properties of ZnO-SnO2 ceramics have been studied. Starting powders of ZnO and SnO2 were mixed in the molar ratio ...
