ABSTRACT |
Dielectric hysteresis characteristics of Pb(Zr0.52Ti0.48)O3 ceramics have been investigated as a function of the amount of MnO2 addition ranged from 0.0 wt% in Pb(Zr0.52Ti0.48)O3 ceramics enhanced the dielectric strength, aging effect and remanent polarization, while reduced the coercive field. These results could be explained by the effect of Mn-Vo association due to the substitution of Mn for the (Zr, Ti) site in PZT. |
