Characterization of pressure-less sintered MgO-Al2O3-SiO2-TeO2 system
(Belgrade : Materials Research Society of Serbia, 2017)
In this study, sintering of two systems was investigated in parallel, pure cordierite 2MgO:2Al2O3:5SiO2, and cordierite with addition of 5 mass % TeO2. Green bodies were prepared from powder mixtures mechanically activated ...
Structural characterization and electrical properties of sintered magnesium-titanate ceramics
(Belgrade : Materials Research Society of Serbia, 2012)
In this article the influence of ball milling process on structure of MgO-TiO2 system, along with its influence on electrical properties of post-sintering samples, were investigated. Mixtures of MgO-TiO2 powders were ...
Electrical and mechanical properties of alumina doped with transition metal oxides sintered at 1400°C
(Societa ceramica italianaPolitecnico di Torino, 2019)
Corundum (alpha-alumina) is one of the most exploited materials in ceramic industry due to its good physico-chemical properties, mechanical properties, and, importantly, due to its low cost. Advantageous properties, such ...
Synthesis and Characterization of Multifferoics 16%(Fe2O3)4%(BaCO3)80%(BaTiO3)
(Belgrade : Serbian Ceramic Society, 2017)
The initial powder (16 % Fe2O3, 4 % BaCO3, 80 % BaTiO3) was mechanically activated in a planetary mill for 20, 80, 120, 160, 200 and 220 minutes in air. Modified Faraday method was used to perform magnetization measurements ...
The Influence of Mechanical Activation on Sintering Process of BaCO3-SrCO3-TiO2 System
(Belgrade : Serbian Ceramic Society, 2012)
In this article the influence of mechanical activation on sintering process of barium-strontiumtitanate ceramics has been investigated. Both non-activated and mixtures treated in planetary ball mill for 5, 10, 20, 40, 80 ...
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 ...
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 ...
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 ...
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 ...
