Electrical properties of ZnO varistors prepared by direct mixing of constituent phases
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Varistor samples containing different amounts of constituent phases were prepared by direct mixing of constituent phases. Detailed electrical characterization was performed to explain the influence of minor phases (spinel ...
Spark plasma sintering of hydrothermally synthesized bismuth ferrite
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2016)
Bismuth ferrite, BiFeO3 (BFO), powder was synthesized by hydrothermal method from Bi(NO3)(3)center dot 5H(2)O and Fe(NO3)(3)center dot 9H(2)O as precursors. The synthesized powder was further sintered using spark plasma ...
Nanostructured Fe2O3/TiO2 thick films prepared by screen printing
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2013)
Nanostructured single layered (pure TiO2, pure alpha-Fe2O3 and mixed Fe2O3/TiO2 with two different oxide ratios, 2 : 3 and 3 : 2) and double layered (TiO2 layer over a Fe2O3 layer) thick films have been fabricated by screen ...
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 ...
Effects of strontium doping on microstructure and functional properties of solution-derived potassium sodium niobate thin films
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2020)
The effects of strontium doping (0-2 mol%) on structure, microstructure and functional properties of potassium sodium niobate (KNN) thin films deposited on Pt(111)/TiOy/SiO2/Si substrates were investigated. Incorporation ...
Microstructural, Thermoelectric and Mechanical Properties of Cu Substituted NaCo2O4
(MDPI, 2022)
Polycrystalline samples of NaCo2−xCuxO4 (x = 0, 0.01, 0.03, 0.05) were obtained from powder precursors synthesized by a mechanochemically assisted solid-state reaction method (MASSR) and a citric acid complex method (CAC). ...
Comparison of two alkali-activated systems: mechanically activated fly ash and fly ash-blast furnace slag blends
(Elsevier Science Bv, Amsterdam, 2015)
Poor reactivity of fly ash (FA) in alkali activation process can be improved either by mechanical activation of fly ash or by blending fly ash with more reactive material, such as blast furnace slag (BFS). Both options ...
Microstructural analysis of Bulk Molding Compounds and correlation with the flexural strength
(Mednarodna podiplomska šola Jožefa Stefana, Ljubljana, 2016)
In this study, the influence of the glass fiber (GF) content on the
microstructure and flexural strength of bulk molding compounds (BMCs) is
investigated. Three sets of BMCs with different weight fractions of GF
(5/10/12.5 ...
NIOBIUM DOPED BARIUM BISMUTH-TITANATE CERAMICS
(Faculty of Technology, University of Novi Sad Bul. cara Lazara 1, 21000 Novi Sad, Serbia, 2011)
Ferroelectric materials with diffuse phase transition (DPT) charactreristics and/or
relaxor properties have been exstensively studied in the last few decades mainly due to
their very interesting and still not completely ...
STRUCTURAL AND MICROSTRUCTURAL CHARACTERIZATION OF BST CERAMICS OBTAINED BY HYDROTHERMALLY ASSISTED COMPLEX POLYMERIZATION METHOD
(Institute for Multidisciplinary Research, University of Belgrade, 2013)
Barium strontium titanate powder Ba0.8Sr0.2TiO3 (BST) has been obtained by hydrothermal treatment of precursor solution containing titanium citrate, previously prepared by complex polymerization method, and barium and ...
