The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Belgrade : Serbian Ceramic Society, 2013)
Ferroelectric ceramic barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using starting powders of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide (TiO2-anatase). ...
Influence of prolonged sintering time on density and electrical properties of isothermally sintered cordierite-based ceramics
(Belgrade : International Institute for the Science of Sintering, 2013)
Mechanical activation is a commonly used and relatively fast and inexpensive procedure for sample preparation before the sintering process. Cordierite, a stoichiometric mixture of three different oxides (2MgO⋅2Al2O3⋅5SiO2) ...
Sintering of the mechanically activated MgO-TiO2 system
(Hanyang University Press, 2013)
Mixtures of MgO-TiO2 powders were mechanically activated in a planetary ball mill for a time interval from 0 to 120 minutes. The influence of the mechanical activation on the phase composition and crystal structure have ...
