Synthesis and sintering of high-temperature composites based on mechanically activated fly ash
(Belgrade : International Institute for the Science of Sintering, 2012)
Amount of fly ash which is and yet to be generated in the coming years highlights the necessity of developing new methods of the recycling where this waste can be reused in significant quantity. A new possibility for fly ...
Influence of Bi2O3 on microstructure and electrical properties of ZnO-SnO2 ceramics
(Belgrade : International Institute for the Science of Sintering, 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 ...
Ho2O3 Additive Effects on BaTiO3 Ceramics Microstructure and Dielectric Properties
(Belgrade : International Institute for the Science of Sintering, 2012)
Doped BaTiO 3-ceramics is very interesting for their application as PTCR resistors, multilayer ceramic capacitors, thermal sensors etc. Ho doped BaTiO 3 ceramics, with different Ho 2O 3 content, ranging from 0.01 to 1.0 ...
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 ...
Mechanical properties and microstructure fractal analysis of refractory bauxite concrete
(Belgrade : International Institute for the Science of Sintering, 2015)
The surface topography analysis via fractals as a means of explanation of composite materials mechanical and microstructural characteristics has hardly been reported so far. This study proposes a method of fractal analysis ...
Investigation of sintering kinetics of ZnO by observing reduction of the specific surface area
(Belgrade : International Institute for the Science of Sintering, 2007)
Reduction of the specific surface area of porous ZnO during the sintering process was studied. ZnO powder was sintered at temperatures from 673 K to 1173 K. The decrease in the specific surface area was observed as a ...
Analysis of isothermal sintering of zinc-titanate doped with MgO
(Belgrade : International Institute for the Science of Sintering, 2007)
The aim of this work was analysis of isothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO2 and MgO (0, 1.25 and 2.5%) were mechanically activated 15 minutes ...
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 ...
Thermal diffusivity of sintered 12CaO-7Al2O3
(Belgrade : International Institute for the Science of Sintering, 2003)
The thermal diffusivity and some electrical transport properties of sintered 12CaO-7Al2O3 were determined using a photoacoustic method with a transmission detection configuration. The thermal diffusivity, coefficient of ...
Synthesis of BaTiO3 from a mechanically activated BaCO 3-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2008)
In this article the solid state reaction of BaTiO3 formation from a mechanically activated BaCO3-TiO2 system has been investigated. An equimolar mixture of BaCO3 and TiO2 powders was activated in a planetary ball mill in ...
