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 ...

(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 ...
Electrical properties of magnesium titanate ceramics post-sintered by hot isostatic pressing
(Belgrade : International Institute for the Science of Sintering, 2017)
Post-sintering of magnesium titanate ceramics by hot isostatic pressing (HIP) in an oxygen-free atmosphere significantly alters various electrical properties of the product. In particular, the sintered material becomes a ...
Metal rings and discs Matlab/Simulink 3D model for ultrasonic sandwich transducer design
(Belgrade : International Institute for the Science of Sintering, 2012)
Metal-endings are integral part of different ultrasonic sandwich transducers. In this paper a new Matlab/Simulink 3D model of of the finite metal rings and discs of various dimensions is realized. With this model, which ...
Synthesis and characterization of zinc titanate nano-crystal powders obtained by mechanical activation
(Belgrade : International Institute for the Science of Sintering, 2005)
Development of dielectric materials for microwave frequencies is increasing with rapid progress in mobile and satellite communications systems, where zinc titanates have found application due to their semi-conducting and ...
Analysis and modeling of sintering of Sr-hexaferrite produced by PIM technology
(Belgrade : International Institute for the Science of Sintering, 2011)
The powder injection moulding (PIM) technology is lately becoming more and more significant due to complex design possibilities and good repeatability. This technology requires optimization of all steps starting with ...
Influence of dimensionality on phase transition in VO2 nanocrystals
(Belgrade : International Institute for the Science of Sintering, 2013)
Hydrothermally synthesized one-dimensional and two-dimensional nanocrystals of VO2 undergo phase transition around 65°C, where temperature and mechanism of phase transition are dependent on dimensionality of nanocrystals. ...
Investigation of sintering kinetics of NiO using photo acoustic spectroscopy
(Belgrade : International Institute for the Science of Sintering, 2004)
Sintering kinetics of NiO was investigated using photo acoustic spectroscopy This method was used to follow the change of phase and amplitude of the photo acoustic signal of nickel-oxide samples sintered at 1373 K for ...
Far infrared properties of sintered PbTe doped with boron
(Belgrade : International Institute for the Science of Sintering, 2007)
Far infrared spectra of sintered PbTe doped with boron were analyzed. The measured infrared spectra were fitted using a modified plasmon-phonnon interaction model with two additional oscillators (at about 195 cm-1 and 285 ...
