Thermal diffusivity of sintered 12CaO-7Al2O3
(Belgrade : International Institute for the Science of Sintering, 2003)
The thermal diffusivity and some electrical transport properties of sintered 12CaO-7Al2O3 were determined using a photoacoustic method with a transmission detection configuration. The thermal diffusivity, coefficient of ...
Sintering of mechanically activated Zno-TiO 2 powders
(Springer, 2008)
Zinc oxide and titanium dioxide powders mixed in an equimolar ratio are mechanically activated in a planetary ball mill and sintered under nonisothermal and isothermal conditions. Nonisothermal sintering is studied using ...
Analysis of nonisothermal sintering of zinc-titanate ceramics doped with MgO
(Springer, 2008)
The aim of this work is to analyze nonisothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO 2, and MgO (0, 1.25, and 2.5%) are mechanically activated for 15 ...
Application of the master sintering curve theory to non-isothermal sintering of BaTiO3 ceramics
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
In this paper a practical approach to the analysis of sintering of BaTiO3 using the Master Sintering Curve concept has been presented. Non-isothermal sintering of high-purity non-doped BaTiO3 ceramics was monitored using ...
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 ...
The influence of mechanochemical treatment of the Bi2O3-ZrO2 system on the structural and dielectric properties of the sintered ceramics
(Kluwer Academic Publishers, 2004)
A powder mixture of alpha-Bi2O3 and ZrO2, both monoclinic, in the molar ratio 2:3, was mechanochemically treated in a planetary ball mill in an air atmosphere for up to 20 h, using steel vial and hardened-steel balls as ...
Ispitivanje sinterovane cink-kalaj-oksidne keramike fotoakustičnom spektroskopijom
(Beograd : Savez hemijskih inženjera, 2007)
Prahovi ZnO i SnO2 pomešani u molamom odnosu 2:1 mehanički su aktivi- rani u planetamim mlinu sa kuglama u intervalu od 10 do 160 minuta. Do- bijene smeše presovane su i izotermski sinterovane na 1300 °C, dva sata. Uzorci ...
The Influence of Milling Conditions on Mechanochemical Synthesis and Sintering of Zinc Titanate
(Kyiv : G. V. Kurdyumov Institute for Metal Physics of the National Academy of Sciences of Ukraine, 2006)
The aim of this work was an investigation of experimental conditions for mechanochemical synthesis and sintering of spinel zinc titanate (Zn2TiO4). Starting powder mixtures of zinc oxide and titan dioxide in the molar ...
