Ferroelectric Properties and Internal Friction in Doped PZT Ceramics

Abstract:

Multicomponent PZT-type solid solution with composition: Pb_0.975Ba_0.01Ca_0.01Sr_0.005 (Zr_0.52Ti_0.48)O₃+1.4wt.%Bi₂O₃+0.3wt.%GeO obtained by hot uniaxial pressing method is described in this paper. There are presented the results of studies of structural, dielectric and internal friction of obtained multicomponent PZT-type ceramics. It has been stated that the dielectric anomalies and internal friction anomalies are observed in similar temperature ranges. Obtained PZT-type ceramics have high value of the dielectric permittivity and low dielectric losses. The high temperature of phase transition and high value of electric permittivity allow considering this material as a base for low frequency and high temperature electromechanical transducers.
