Ferroelectric Properties and Internal Friction in Doped PZT Ceramics
Multicomponent PZT-type solid solution with composition: Pb0.975Ba0.01Ca0.01Sr0.005 (Zr0.52Ti0.48)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.
