Microstructural and electrical properties of cordierite-based ceramics obtained after two-step sintering technique
(Science of Sintering, 2016)
Cordierite-based ceramic materials are attracting much interest for their various applications in industry, for manufacturing multilayer circuit boards, catalytic converters, filters, thermal insulation, kiln furniture, ...
Sintering of mechanically activated magnesium-titanate and barium-zinc-titanate ceramics
(Belgrade : International Institute for the Science of Sintering, 2011)
In this article the influence of mechanical activation on sintering process of magnesium-titanate and barium-zinc-titanate ceramics has been investigated. Both nonactivated and mixtures treated in planetary ball mill for ...
Influence of mechanical activation on microstructure and crystal structure of sintered MgO-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2010)
Mixtures of MgO-TiO2 were mechanically activated using high-energy planetary ball mill during 5, 10, 20, 40, 80 and 120 minutes. Sintering process was preformed in air at 1100o-1400oC for 2h. The decrease in powder’s ...
Study of dielectric behavior and electrical properties of hematite α-Fe2O3 doped with Zn
(Belgrade : International Institute for the Science of Sintering, 2012)
The effects of Zn-doping on the dielectric behavior and electrical properties of bulk α-Fe2O3 have been studied. X-ray diffraction analysis revealed the presence of two phases in all samples: hematite and spinel ZnFe2O4, ...
Natural Diatomite (Rudovci, Serbia) as Adsorbent for Removal Cs from Radioactive Waste Liquids
(Science of Sintering, 2015)
The removal of Cs (I) ions from aqueous solution was studied using natural diatomite as adsorption materials originated from Rudovci, Serbia. The microstructure of natural diatomite has been characterized by X-ray diffraction ...
Two step sintering of ZnTiO3 nanopowder
(Belgrade : International Institute for the Science of Sintering, 2017)
Metastable nanopowder ZnTiO3 was pressed into cylindrical compacts at 200 MPa. Compacts were treated by conventional heating with isothermal holding at 931°C for 10 minutes, 25 minutes and 40 minutes. ZnTiO3 compacts were ...
Discrete temperature values in the sintering process as a BaTiO3-ceramics properties parameter
(Belgrade : International Institute for the Science of Sintering, 2017)
In this paper, we develop the new physical-mathematical time scale approach-model applied to BaTiO3-ceramics. At the beginning, a time scale is defined to be an arbitrary closed subset of the real numbers R, with the ...
Solid state synthesis of extra phase-pure Li4Ti5O12 spinel
(Belgrade : International Institute for the Science of Sintering, 2011)
Extra phase-pure Li4Ti5O12 spinel with particle sizes less than 500 nm was synthesized by solid state reaction of mechanochemicaly activated mixture of nano anatase and Li2CO3 for a very short annealing time, 4 h at 800°C. ...
Investigation of sintering kinetics of magnesium titanate
(Belgrade : International Institute for the Science of Sintering, 2013)
Obtaining new materials including sintered electronic materials using different procedures is the consequence of long complex and expensive experimental work. However, the dynamics of expansive development of electronic ...
Non-isothermal crystallization of lithium germanophosphate glass studied by different kinetic methods
(Belgrade : International Institute for the Science of Sintering, 2018)
Crystallization kinetics of 22.5Li2O•10Al2O3 •30GeO2•37.5P2 O5 (mol%) glass was studied under non-isothermal condition using the differential thermal analysis (DTA). The study was performed by using the first crystallization ...
