Mechanical activation as sintering pre-treatment of talc for steatite ceramics
(Belgrade : Interenational Institute for the Science of Sintering, 2014)
The effect of vibratory mill induced mechanical activation on the change of the particle size, crystallinity and the phase transformations of the minerals present in the activated material, was studied with the purpose of ...
Influence of Point Defects Concentration on Densification Process and Optical Properties of Sintered ZnO Ceramics
(Belgrade : Materials Research Society of Serbia, 2015)
Zinc oxide is one of the most studied materials due to its potential applications in electronics, optoelectronics and spintronics. In the forms of single crystal and thin-film ZnO could be used as UV and blue light emitter, ...
Shungite – a carbon-mineral rock material: Its sinterability and possible applications
(Novi Sad : Faculty of Technology, University of Novi Sad, 2019)
The paper presents results of the influence of mechanical activation of shungite, a carbon-mineral rock material rich in silica and carbon, on its sintering behaviour, and obtaining of pure SiC ceramics. The mechanical ...
Characterisation of Mn0.63Zn0.37Fe2O4 powders after intensive milling and subsequent thermal treatment
(Science of Sintering, 2017)
Commercial Mn-Zn powder (Mn0.63Zn0.37Fe2O4, 93 wt. % and Fe2O3 7 wt. %) was milled 0.5, 1, 2 and 4 hours in a planetary ball mill. The goal was to observe intensive milling influences on oxidation and reduction processes ...
Properties of Magnesium Titanate Ceramic Obtained by Two Stage Sintering
(Belgrade : Serbian Ceramic Society, 2014)
The aim of this paper was investigation of structural and electrical properties of magnesium titanate ceramic obtained mechanochemically and subjected to two stage sintering process. Mixtures of MgO and TiO2 were treated ...
Physical Properties of Sintered Alumina Doped with Different Oxides
(Belgrade : ETRAN, 2018)
Corundum (α-alumina) is a suitable material for usage in various industry fields owing to its chemical stability, electrical and mechanical features. It is known that properties of ceramics could be modified by addition ...
Structure and photocatalytic properties of sintered TiO2 nanotube arrays
(Belgrade : ETRAN, 2018)
One-dimensional (1D) TiO2 nanotubes perpendicular to the substrate were obtained by electrochemical oxidation of titanium foil in an acid electrolyte. In order to alter the crystallinity and the morphology of films the ...
Effects of mechanical-activation and TiO2 addition on the behavior of two-step sintered steatite ceramics
(Elsevier, 2019)
Steatite, as ceramic with composition predominantly resting on magnesium silicate, was produced from economic resources – talc, aluminosilicate clays, and either BaCO3 or feldspar as flux. Titanium dioxide was a doping ...
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 ...
