Electrical Properties of Un-doped and Doped EuTiO3-based Perovskites [PDF]

, 2013
Un-doped and doped EuTiO3 (ET) ceramics were prepared in 5%H2/95%N2 and N2 atmospheres at various temperatures (1350, 1450 and 1500 oC). For un-doped ET, higher pellet density (above 90%) and larger grain sized ceramics were obtained from the higher ...

Effect of sintering temperature and heat treatment on electrical properties of indium oxide based ceramics [PDF]

, 2008
Indium oxide based ceramics with bismuth oxide addition were sintered in air in the temperature range 800-1300 ºC. Current-voltage characteristics of In2O3-Bi2O3 ceramics sintered at different temperatures are weakly nonlinear.
