Influence of one activated component on the sintering process of three phase system
(Belgrade : Materials Research Society of Serbia, 2013)
According to its low temperature thermal expansion coefficient, low dielectric constant, also good mechanical properties, cordierite, 2MgO×2Al2O3×5SiO2, represents a very attractive hightemperature ceramic material. In ...
Reaction kinetics of mechanically activated cordierite based ceramics studied via DTA
(Ljubljana : Central and Eastern European Committee for Thermal Analysis and Calorimetry, 2015)
Cordierite, 2MgO•2Ah03•5Si02 (MAS), is a very attractive high-temperature ceramic material. In order to accelerate the process of sintering, 5.00 mass% Mo03 was added to the starting mixtures. The mechanical activation of ...
Characterization of MgAl2O4 sintered ceramics
(Belgrade : Serbian Ceramic Society, 2019)
Single crystalline phase MgAl2O4 is made from the predetermined composition of MgO-Al2O3 powder mixture by using ball-milling. Mixtures of MgO and Al2O3 are treated in planetary ball mill for 30, 60, 90 and 120 minutes, ...
Sintering of cordierite in the presence of MoO3 and crystallization analysis
(Belgrade : Materials Research Society of Serbia, 2014)
Cordierite (MAS) is difficult to sinter because of the very narrow sintering temperature range (1300-1400ºC). Because a low temperature process is desirable, it is necessary to find functional ads which can allow easier ...
Shungite - a Russian mineral: possible application as a microwave absorber
(Belgrade : Materials Research Society of Serbia, 2018)
The paper presents results of investigation of the influence of mechanical activation of shungite, a Russian natural mineral rich in silica and carbon, on its sintering behavior. The mechanical activation of the starting ...
Influence of MoO3 on cordierite ceramics sintering and crystallization
(Belgrade : Materials Research Society of Serbia, 2013)
The influence of MoO3 on the process of cordierite ceramics preparation, 2MgO-2Al2O3-5SiO2 (MAS) was researched by sintering followed binary systems: MgO/MoO3 (sintered at 850 ºC and 1000 ºC), Al2O3/Bi2O3 and SiO2/Bi2O3 ...
Adsorption capacity of wollastonite based adsorbents with porous structure controlled with different progeny agents
(Belgrade : Serbian Ceramic Society, 2016)
Porous wollastonite (WL) based adsorbents were fabricated by a pressureless sintering process by using low molecular weight poly(methyl methacrylate) (PMMA), nanocellulose (NC) and yeast as the pore forming agents. WL based ...
Microstructure evolution and sintering kinetics of ZnO
(Belgrade : Institute of Technical Sciences of SASA, 2010)
The aim of this paper was to analyse the sintering kinetics and microstructure evolution of ZnO. Powder was isothermally sintered (15, 30, 60, 90 and 120 minutes) in the temperature range from 800 to 1200oC. The values of ...

(2013)
Poster presented at the conference Advanced Ceramics and Application II – Serbian Ceramic Society, Belgrade, September 30 – October 1, 2013
Influence of different pore-forming agents on wollastonite microstructures
(Belgrade : Serbian Ceramic Society, 2016)
In this study, highly porous macro- and micro-cellular wollastonite-based ceramics was synthesized. Ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as starting material. After 20 min ...
