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 ...
Sintering effects on microstructure and dielectric properties of CCTO ceramics
(Belgrade : Materials Research Society of Serbia, 2012)
A perovskite-type compound, calcium copper titanate (CaCu3Ti4O12, CCTO) attracted ever increasing attention for its practical applications in microelectronics, especially for preparation of capacitors and memory devices. ...
DSC-TG-MS study of hydroxyapatite nanopowders
(Belgrade : Institute of Technical Sciences of SASA, 2013)
Hydroxyapatite nanopowders have been widely studied for biomedical application due to excellent biocompatibility. It attaches chemically to bone tissue providing fixation of artificial implant materials. Main research ...
Bi2O3 influence on electronic ceramics sintering process and final properties
(Belgrade : Association of Metallurgical Engineers of Serbia (AMES), 2019)
The influence of Bi2O3 as a functional additive on the process of obtaining cordierite, 2MgO-2Al2O3-5SiO2 (MAS) was studied by sintering the MgO / Bi2O3 system (sintered at 820 °C and 1100 °C), Al2O3 / Bi2O3 and SiO2 / ...
Activation and relaxation time influence on cordierite ceramics
(Belgrade : Association of Metallurgical Engineers of Serbia (AMES), 2019)
Mechanochemical activation of 2MgO•2Al2O3•5SiO2, starting components of cordierite, was used in aim to decrease the sintering temperature. Cordierite is very attractive ceramic material due to its properties, excellent ...
Influence of nitrogen and air atmosphere during thermal treatment on micro and nano sized powders and sintered TiO2 specimens
(Science of Sintering, 2014)
The influence of air and nitrogen atmosphere during heating on TiO2 nano and micro sized powders as well as sintered polycrystalline specimens was analyzed. Sintering of TiO2 nano and micro powders in air atmosphere was ...
Isothermal sintering of barium-zinc-titanate ceramics
(Oxford : Elsevier Sci Ltd., 2011)
Mixtures of BaCO3-ZnO-TiO2 were mechanically activated using high-energy planetary ball mill during 20, 40 and 80 min. As the time of mechanical activation increased, the decrease in particle size was observed. The effect ...
