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 ...
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 ...
THE RELATIONSHIP BETWEEN FLY ASH-BASED GEOPOLYMER STRENGTH AND MAJOR STRUCTURAL ELEMENTS
(Institute for Multidisciplinary Research, University of Belgrade, 2013)
Geopolymers are relatively new type of inorganic binder materials, which can partly substitute Portland cement. Application of geopolymer binders is very favorable from ecological point of view for two reasons: because of ...
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 ...
Microstructure, mechanical and electrical properties of Glass Fiber Reinforced Composites (GFRC)
(Mednarodna podiplomska ²ola Joºefa Stefana, Ljubljana, 2015)
In this study, the influence of E-glass fiber and mineral filler content
on the microstructure, physical, mechanical and dielectric properties of Glass
Fiber Reinforced Composites (GFRC) was investigated. Five sets of ...
TEM and FESEM investigation of lanthanum nickelate thin films obtained by chemical solution deposition
(University of Novi Sad, 2012)
Lanthanum nickelate (LNO) is a perovskite oxide material with metallic conductivity in a wide temperature
range which makes it suitable for application as electrode material for thin films. In this paper LNO thin films
were ...
EFFECT OF LANTHANUM ON MICROSTRUCTURE OF BaTiO3: PREPARED BY POLYMERIC PRECURSORS METHOD
(3'd Workshop Nanostructured Materials : Processing and Application September 2, 2007 Bled, Slovenia, 2007)
Due to its high dielectric constant and low loss characteristics, barium titanate has
been used in many applications, such as capacitors, piezoelectric devices, positive
temperature coelficient thermistors, semiconductors ...
