The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Belgrade : Serbian Ceramic Society, 2013)
Ferroelectric ceramic barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using starting powders of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide (TiO2-anatase). ...
Preparation and characterization of Cu and Zn modified nickel manganite NTC powders and thick film thermistors
(Elsevier, 2013)
A simple ball milling/thermal treatment procedure was applied to obtain fine thermistor powders. Three different powder compositions were analyzed–Cu0.2Ni0.5Zn1.0Mn1.3O4, Cu0.25Ni0.5Zn1.0Mn1.25O4 and Cu0.4Ni0.5Mn2.1O4. XRD ...
Sintering Effects on Microstructure and Electrical Properties of CaCu3Ti4O12 Ceramics
(Hoboken, NJ : John Wiley & Sons, 2013)
CCTO powders were prepared by solid state reaction and mechanochemically, respectively. Synthesized powders were characterized by XRD, FE-SEM and PSA techniques. The sinterability of CCTO powders was investigated by heating ...
Structural and electrical properties of Ti doped α-Fe2O3
(Belgrade : International Institute for the Science of Sintering, 2013)
In this work we have analyzed the effects of Ti doping on structural and electrical properties of α-Fe2O3. When the amount of added Ti (5 wt.%TiO2) was within the solubility degree and XRD, SEM and EDS analysis revealed a ...

Uticaj parametara sinteze i strukture na električna svojstva Ba0,77Sr0,23TiO3
(Čačak : University of Kragujevac, Faculty of Technical Sciences, 2013)
Rezultati istraživanja u oblasti elektronske keramike u najvećoj meri direktno zavise od poznavanja procesa konsolidacije (presovanje i sinterovanje) keramičkih prahova, što, posmatrano sa gledišta poimanja prirode, ukazuje ...
Influence of prolonged sintering time on density and electrical properties of isothermally sintered cordierite-based ceramics
(Belgrade : International Institute for the Science of Sintering, 2013)
Mechanical activation is a commonly used and relatively fast and inexpensive procedure for sample preparation before the sintering process. Cordierite, a stoichiometric mixture of three different oxides (2MgO⋅2Al2O3⋅5SiO2) ...
Sintering of the mechanically activated MgO-TiO2 system
(Hanyang University Press, 2013)
Mixtures of MgO-TiO2 powders were mechanically activated in a planetary ball mill for a time interval from 0 to 120 minutes. The influence of the mechanical activation on the phase composition and crystal structure have ...
