Influence of mechanical activation on synthesis and properties of the MgO-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2007)
Materials applied in electronics such as multilayer capacitors are an important field of ceramic materials. Magnesium titanate based dielectric materials are used for producing type-I capacitors. A common way of obtaining ...
Influence of Gd-doping on electrical properties in Ca1-xGdxMnO3 (x=0.05, 0.1, 0.15, 0.2) perovskites
(Belgrade : Institut za multidisciplinarna istraživanja, 2023)
Ca1-xGdxMnO3 (x = 0.05–0.20) nanostructured perovskites were successfully synthesized by modified glycine nitrate procedure (MGNP). Temperature intervals of sintering and phase transition during heating were revealed during ...
BaTi0.975Sn0.025O3/BaTi0.85Sn0.15O3 functionally graded materials: master sintering curves and electrical properties
(Belgrade : Institute of Technical Sciences of SASA, 2009)
The most important aim in the design and processing of functionally graded materials (FGMs) is to obtain high-quality microstructure, and to produce devices free from any form of deformation. During sintering of BTS2.5/BTS15 ...
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 ...
Electronic properties of BZT nano-ceramic grades at low frequency region
(Belgrade : ETRAN, 2023)
BZT ceramics was prepared by using fine powder mixture of BaCO3, TiO2 and ZrO2 in the respective molar ratio to form Ba(Zr0.10Ti0.90)O3 via solid state reaction at elevated temperature. The prepared BZT was milled in the ...
Characterization of NTC thick film thermistor paste Cu0.2 Ni0.5 Zn1.0 Mn1.3O4
(Belgrade : Serbian Ceramic Society, 2023)
A powder of Cu0.2Ni0.5Zn1.0 Mn1.3O4 composition for custom thermistor was prepared by using a certain mixture of metal oxides and solid state reaction at 1000 °C/4h in air. The obtained thermistor powder was milled in the ...
Final‐stage densification kinetics of direct current–sintered ZrB2
(Wiley, 2023)
Final-stage sintering was analyzed for nominally phase pure zirconium diboride synthesized by borothermal reduction of high-purity ZrO2. Analysis was conducted on ZrB2 ceramics with relative densities greater than 90% using ...
