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 ...
Structural and electrical properties of sintered Fe2O3/TiO2 nanopowder mixtures
(Elsevier Sci Ltd, Oxford, 2014)
Starting nanopowders of TiO2 (anatase 99.7%) and alpha-Fe2O3 (hematite) were mixed in the weight ratios 60:40 and 40:60. Green samples were sintered in the temperature range 750-1250 degrees C in air. Structural, morphological ...
Antimony doping effect on barium titanate structure and electrical properties
(Elsevier Sci Ltd, Oxford, 2011)
Nanopowders of pure and antimony doped barium titanate (BaTiO3-BT) were synthesized by polymeric precursors method based on Pechini process. Obtained powders were pressed and sintered at 1300 degrees C for 8 h. XRD analysis ...
Electrical Properties of Inkjet Printed Graphene Patterns on PET-Based Substrate
(IEEE Computer Society, 2015)
In this paper, electrical properties of inkjet printed graphene patterns on a PET-based (Novele (TM) IJ-220) substrate are presented. Water-soluble graphene conductive ink (Phene plus I3015) was used. Tested samples were ...
Change in structural, ferroelectric, and magnetic properties of bismuth ferrite induced by doping with gadolinium
(Elsevier Sci Ltd, Oxford, 2019)
Bismuth ferrite, BiFeO3, was doped with a wide range of concentrations (0-30%) of Gd in order to investigate structural, ferroelectric, and magnetic properties and their correlation. Powder samples of Bi1-xGdxFeO3 (x = ...
The characterization of the barium titanate ceramic powders prepared by the Pechini type reaction route and mechanically assisted synthesis
(Elsevier Sci Ltd, Oxford, 2010)
BaTiO3 ceramic powders were prepared by a complex method based on the Pechini type reaction route and mechanically assisted synthesis. In both ways BaTiO3 ceramics were sintered after 120 min on 1300 degrees C without ...
Influence of mechanochemical activation on the sintering of cordierite ceramics in the presence of Bi2O3 as a functional additive
(Elsevier, Amsterdam, 2012)
Due to its outstanding electrical characteristics, such as the low temperature expansion coefficient, low dielectric constant and good mechanical properties, cordierite, 2MgO center dot 2Al(2)O(3)center dot 5SiO(2), is a ...
Characterisation of Mn0.63Zn0.37Fe2O4 Powders After Intensive Milling and Subsequent Thermal Treatment
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
Commercial Mn-Zn powder (Mn0.63Zn0.37Fe2O4, 93 wt. % and Fe2O3 7 wt. %) was milled 0.5, 1, 2 and 4 hours in a planetary ball mill. The goal was to observe intensive milling influences on oxidation and reduction processes ...
Structure and photocatalytic properties of sintered TiO2 nanotube arrays
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
One-dimensional (1D) TiO2 nanotubes perpendicular to the substrate were obtained by electrochemical oxidation of titanium foil in an acid electrolyte. In order to alter the crystallinity and the morphology of films the ...
Nanostructured Fe2O3/TiO2 thick films: Analysis of structural and electronic properties
(Elsevier Sci Ltd, Oxford, 2015)
Thick films using starting nanopowders of TiO2 (anatase 99.7%) and alpha-Fe2O3 (hematite) mixed in the weight ratios 60:40 and 40:60 for thick film paste were fabricated by screen printing technology on an alumina substrate. ...
