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 ...
Full density calcium phosphate bioceramics from nanopowders by sintering
Poster presented at the Adriatic School of Nanoscience – ASON-1, Dubrovnik, Croatia, September 19–23, 2010
ZnO varistors prepared by direct mixing of constituent phases
(Sendai : Japan Institute of Metals, 2000)
ZnO varistors with non-linearity coefficients reaching 50 and low values of the leakage current (approximately 0.01 A/m2), were obtained by a method referred to as `direct mixing of constituent phases'. The method is based ...
Uticaj aditiva na sinterovanje sistema ZnO-TiO2 saglasno trijadi sinteza-struktura-svojstva
(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2007)
U okviru ove doktorske disertacije detaljno i sistematski je proučen uticaj aditiva magnezijum oksida na sintezu i sinterovanje sistema ZnO-TiO2. Smeša prahova ZnO, TiO2, MgO (0, 1,25 i 2,50 masenih % MgO), mehanički je ...
Reduction of the specific surface area of porous ZnO during sintering
(Čačak : Technical Faculty, 2007)
In this paper reduction of the specifice surface area of porous ZnO during sintering was analyzed. ZnO was sintered at temperatures from 673K to 1173K. Reduction of the specific surface area was observed as a function of ...
Tesla's Fountain – Modeling and simulation in ceramics technology
In this paper, we present Tesla's Fountain in ceramics technology reconstruction from basic 3D model, simulation of the engine, light and fluids till the real materialization. As the one of the most important model purposes, ...
Densification rate and phase structure changes during sintering of zinc titanate ceramics
Densification rate and phase structure changes during sintering of nanosized ZnTiO3 were studied. Sintering was performed in a dilatometer in two regimes: the first to 900 °C (heating rates 5, 10 and 15 °C/min) and the ...
Influence of nitrogen and air atmosphere during thermal treatment on micro and nano sized powders and sintered TiO2 specimens
(Belgrade : International Institute for the 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 ...
Statistical Analysis of the Influence of Temperature on Microstructure Contact Surfaces on BaTiO3 -ceramics Doped with Ho2O3
(Belgrade : Serbian Ceramic Society, 2014)
The materials based on BaTiO3 can be controlled using different technological parameters and different additives. We investigate the influence of different temperature levels of sintering (1320°C, 1350°C and 1380°C) on the ...
The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
Magnesium aluminate, MgAl2O4 and other alumina-based spinels are ceramics with high hardness, high melting point and mechanical strenght. Spinels can also be used as dielectrics in microwave applications. The goal of this ...
