Electrical properties of mechanochemically activated cordierite ceramics
(Springer, 2012)
Three-component oxide mixtures were prepared containing MgO, Al 2 O 3 and SiO 2 in a 2 : 2 : 5 ratio with addition of 10% Bi 2 O 3. The mixtures were mechanically activated in a range from 5 to 240 min in a mill with ceramic ...
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 ...
