Effect of processing parameters on structural and morphological Y2O3 :Yb3+/Ho3+ powders characteristics
(Belgrade : Serbian Ceramic Society, 2013)
Up-converting yttrium oxide powders doped with Yb3+ and co-doped with Ho3+ weresynthesized through hydrothermal processing at 200 °C/3 h. Reverse precipitation of the starting nitrates mixture is performed with the help ...
Microstructure evolution and phase transition in Er doped BaTiO3 ceramics
(Belgrade : Serbian Ceramic Society, 2013)
The Er doped BaTiO3 ceramics, with different Er2O3 content, ranging from 0.01 to 1.0 wt% Er, were investigated regarding their microstructural and dielectric characteristics in this paper. Doped BaTiO3 were prepared by ...
Application of Minkowski layer for microalloyed alumo-silicate ceramics grains fractal analysis
(Belgrade : Serbian Ceramic Society, 2013)
Porous aluminium-silicate ceramics, modified by alloying with magnesium and microalloying with alluminium belongs to a group of advanced multifunctional ceramics materials. This multiphase solid-solid system has predominantly ...
Dielectric characterization of microalloyed alumo-silicate ceramics by using linear regression model
(Belgrade : Serbian Ceramic Society, 2013)
In this paper, dielectric characterization of porous alumo-silicate ceramics, modified by alloying with magnesium and microalloying with aluminum, was investigated. Microstructure investigations have revealed non-uniform ...
Aerosol-assisted synthesis of hierarchically organized titania and titanates nanostructures
(Belgrade : Serbian Ceramic Society, 2013)
The aerosol route, representing a feasible bottom-up technique for nanomaterials processing in disperse system, was applied for the low-temperature (T=150 oC) synthesis of spherical, nonagglomerated, hierarchically organized ...
Dilatometric Analysis of Mechanically Activated SrTiO3 Powder
(Belgrade : Serbian Ceramic Society, 2013)
Strontium-titanate powder was mechanically activated in a planetary ball mill for 0, 5, 10, 30, 60, 90 and 120 minutes. Non-isothermal sintering of non-activated and activated SrTiO3 powder samples in the temperature ...
Density and electrical properties of cordierite based ceramics as function of compaction pressure
(Belgrade : Serbian Ceramic Society, 2013)
Mechanical activation is widely used and relatively inexpensive procedure for sintering process sample preparation. However, the influence of pressure, which is used for compaction, has not been completely investigated. ...
Characterization of mechanically activated ZnO powder
(Belgrade : Serbian Ceramic Society, 2013)
Materials based on ZnO structure have more frequently application as fillers in polymer ceramics nanocompozites. Performances of these materials depends on fillers morphology, surfaces texture and particles size. According ...
Influence of MoO3 on sintering temperature of mechanically activated MgO-Al2O3-SiO2 system
(Belgrade : Serbian Ceramic Society, 2013)
Cordierite, 2MgO⋅2Al2O3⋅5SiO2, is a very attractive high-temperature ceramic material, due to its outstanding electrical characteristics, such as the low temperature expansion coefficient, low dielectric constant and good ...
