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 ...
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 ...

(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 ...
Processing-Dependent Dielectric and Ferroelectric Properties of BST Ceramics
(Vilnius University, Vilnius, Lithuania, 2014)
Barium strontium titanate, BaxSr1-xTiO3 (BST) ceramics have been extensively used as in a microelectronics due
to its excellent ferroelectric, dielectric, piezoelectric, and pyroelectric properties [1–3]. At room ...
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 ...
Influence of MN doping on the evolution of microstructure and optical properties of mechanically activated SrTiO3 powders
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2022)
Manganese doped SrTiO3 powders with various manganese dioxide weight percentages in the range of 1.5, 3 and 6 wp% were prepared by a solid-state method in the presence of mechanical activation (10, 30 and 120 minutes). A ...
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 ...
Influence of lanthanum doping on properties of BaTiO3 prepared from organometallic complex
(5th Workshop COST 539, 1 September 2008, Manchester, UK, abstracts and CD proceedings, 2008)
Barium titanate is the first discovered ferroelectric ceramic and one of the most widely used material for various applications. Doping of BaTiO3 (BT) ceramics is very important for obtaining very interesting characteristics ...
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 ...
