Analysis of nonisothermal sintering of zinc-titanate ceramics doped with MgO
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 ...
Sintering of mechanically activated Zno-TiO 2 powders
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 ...
Phase Formation at the Sintering of Sa, Zn, Ti Oxides
Complex compounds with oxide phases of Ba, 2n, and 11 are widely used in instrument engineering. It is also important to find such production routes for ceramics, which provide their stable structure and properties. Phase ...
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 ...
Influence of mechanical activation on structural and electrical properties of sintered MgTiO3 ceramics
(Belgrade : International Institute for the Science of Sintering, 2009)
The aim of this work was to analyze the influence of mechanical activation on the MgCO3-TiO2 system. Mixtures of MgCO3-TiO2 were mechanically activated for 15, 30, 60 and 120 minutes in a planetary ball mill and after that ...
The master sintering curves for BaTi0.975Sn0.025O3/BaTi0.85S n0.15O3 functionally graded materials
The most important aim in the design and processing of functionally graded materials (FGMs) is to produce devices free from any deformation. Smart choices of different combination of graded layers, as well as the heating ...
Thermal diffusivity of sintered 12CaO×7AI2O3
Poster presented at the 14th International Conference on Photoacoustic and Photothermal Phenomena, Cairo, Egypt, January 6-9, 2007
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 ...
