Abstract
The electrical and mechanical characteristics of Pb n Bi4Ti n +3O3 n +12 ceramics were examined. With increasing n, the dielectric constant ε s increased, and the temperature dependence of ε s broadened. ε s, at room temperature, reached a value of approximately 750 at n=3 and n=4 at 100 kHz. The dielectric breakdown strength E b and the three-point bending strength σ decreased with increasing n. For example, σ of the sample at n=4 was approximately a 70% value of the sample at n=0. On the other hand, the examination of the characteristics of grain-oriented samples clarified that E b and σ can be improved in the direction perpendicular to the polarization axis.
