Formation of porous wollastonite-based ceramics after sintering with yeast as the pore-forming agent
(Belgrade : International Institute for the Science of Sintering, 2017)
In this paper, synthesis of porous wollastonite-based ceramics was reported. Ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as starting material. After 20 min of ultrasound treatment, ...
Effect of chemical composition on microstructural properties and sintering kinetics of (Ba,Sr)TiO3 powders
(Belgrade : ETRAN, 2018)
Barium strontium titanate powders with different Ba:Sr ratios were investigated to determine the influence of the initial composition of powder mixture on microstructural properties and sintering kinetics. It was determined ...
Reheating of zinc-titanate sintered specimens
(Belgrade : International Institute for the Science of Sintering, 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 ...
The thermal and magnetic properties of the Fe89.8Ni1.5Si5.2B3C0.5 and Fe81B13Si14C2 amorphous alloys
(Belgrade : Institute for the Science of Sintering, 2015)
This paper investigates the thermal and magnetic properties of two iron based amorphous alloys with different Fe-content: Fe89.8Ni1.5Si5.2B3C0.5 and Fe81B13Si14C2. The XRD results show that the thermal induced structural ...
Synthesis and characterization of Cu-ZrB2 alloy produced by PM techniques
(Belgrade : International Institute for the Science of Sintering, 2014)
The copper alloy with 7vol.% ZrB2 examined in this study was consolidated via powder metallurgy processing (PM) by combining mechanical alloying and hot pressing process. Structural changes, morphological properties and ...
Impact of crushed mineral aggregate on the pumpability of concrete during transport and placement
(International Institute for the Science of Sintering, 2016)
In the spirit of the sustainable buildings, and with the goal of protection of river courses, in the near future an already announced directive ordering closing down of a large number of river aggregate dredging operations ...
Thermal diffusivity of single crystal Bi0.9Sb0.1
(Belgrade : International Institute for the Science of Sintering, 2010)
A single crystal Bi0.9Sb0.1 ingot was synthesized using the Bridgman technique. Thermal diffusivity and electronic transport properties of single crystal cleaved plates (00l) were determined from PA photoacoustic phase and ...
Sintering of fly ash based composites with zeolite and bentonite addition for application in construction materials
(International Institute for the Science of Sintering, 2017)
Due to pozzolanic characteristics, fly ash is commonly used as a cement replacement in construction composites. Addition of natural clays with sorption ability (i.e. zeolite and bentonite) in to the fly ash based construction ...
Structural and electrical properties of Ti doped α-Fe2O3
(Belgrade : International Institute for the Science of Sintering, 2013)
In this work we have analyzed the effects of Ti doping on structural and electrical properties of α-Fe2O3. When the amount of added Ti (5 wt.%TiO2) was within the solubility degree and XRD, SEM and EDS analysis revealed a ...
Electronic ceramic structure within the Voronoi cells model and microstructure fractals contacts surfaces new frontier applications
(Belgrade : International Institute for the Science of Sintering, 2013)
In this study, in order to establish grain shapes of sintered ceramics, new approach on correlation between microstructure and doped BaTiO3 -ceramics properties based, on Voronoi model and mathematical statistics calculations ...
