The optical and physical properties of PLZT ceramics open a wide spectrum in technical applications for these materials. Because of the wide range of operating conditions for systems under development, careful considerations must be given to the selection of electrostrictive materials.
This paper presents and discusses thermal and frequency properties of electrostrictive transparent PLZT 9/65/35 ceramics at temperatures from –150 to 250 °C and at frequencies from 1 Hz to 100 kHz. The ceramics have been cost efficient produced using an EPD processing chain with nano powders. Ferroelectric polarization versus electric field properties in terms of coercive field Ec and remanent polarization PR were as well examined as the temperature depending ferroelectric hysteresis loop behavior. Additionally thermal and frequency properties of dielectric constant e and dissipation factor tan are shown in detail and compared with other compositions and properties of typical ferroelectric ceramics.
The experimental results presented in this paper finalize the characterization of PLZT specimen produced by a cheap nanopowders and mixed oxide EPD production process already begun in . The results show that careful considerations have to be made in order to select PLZT 9/65/35 material for either low temperature (< –50 °C) or high temperatures (> 100°C) applications, where its properties significantly deviate from its room temperature behavior.
