The influence of mechanical activation on sintering process of BaCO3-SrCO3-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2012)
In this article the influence of mechanical activation on sintering process of bariumstrontium-titanate ceramics has been investigated. Both non-activated and mixtures treated in a planetary ball mill for 5, 10, 20, 40, ...
Peculiarities in sintering behavior of Ca-deficient hydroxyapatite nanopowders
(Elsevier, 2012)
We report unusual sintering behavior of Ca-deficient hydroxyapatite processed with different heating rates; particularly, faster heating resulted in higher densification. We hypothesize that faster heating delays formation ...
Ho2O3 Additive Effects on BaTiO3 Ceramics Microstructure and Dielectric Properties
(Belgrade : International Institute for the Science of Sintering, 2012)
Doped BaTiO 3-ceramics is very interesting for their application as PTCR resistors, multilayer ceramic capacitors, thermal sensors etc. Ho doped BaTiO 3 ceramics, with different Ho 2O 3 content, ranging from 0.01 to 1.0 ...
Synthesis and sintering of high-temperature composites based on mechanically activated fly ash
(Belgrade : International Institute for the Science of Sintering, 2012)
Amount of fly ash which is and yet to be generated in the coming years highlights the necessity of developing new methods of the recycling where this waste can be reused in significant quantity. A new possibility for fly ...
Synthesis of barium-zinc-titanate ceramics
(Belgrade : International Institute for the Science of Sintering, 2012)
Mixtures of BaCO3, ZnO and TiO2 powders, with molar ratio of 1:2:4, were mechanically activated for 20, 40 and minutes in a planetary ball mill. The resulting powders were compacted into pellets and isothermally sintered ...
Influence of mechanochemical activation on the sintering of cordierite ceramics in the presence of Bi2O3 as a functional additive
(Elsevier, 2012)
Due to its outstanding electrical characteristics, such as the low temperature expansion coefficient, low dielectric constant and good mechanical properties, cordierite, 2MgO⋅2Al2O3⋅ 5SiO2, is a very attractive high-temperature ...
Influence of mechanical activation on electrical properties of barium–zinc–titanate ceramics sintered at 1100°C
(Springer US, 2012)
Starting mixtures of BaCO3, ZnO, and TiO2 powders are mechanically activated in a planetary ball mill for various periods of time. The powders obtained are sintered isothermally at 1100°C for 120 min. Non-isothermal sintering ...
