“…As previously discussed, at the temperature range where the material shows incipient piezoelectricity, the electromechanical response is due to repeated poling and depoling originating from a reversible electric‐field‐induced phase transition. As poling/depoling is accompanied by domain switching, the frequency dependence of this extrinsic strain response is expected . The strain at temperatures above 110°C is due to electrostriction and consequently presents negligible frequency dependence.…”

The dielectric and electromechanical properties of 0.75Bi1/2Na1/2TiO3–0.25 SrTiO3 (25ST) as a function of temperature and frequency were studied. It is shown that the 25ST is a relaxor ferroelectric as evidenced by the temperature‐dependent dielectric relaxations with an incipient piezoelectricity featured by the presence of a reversible electric‐field‐induced phase transformation at room temperature. The transition occurs on a broad electric field strength range depending on field amplitude and frequency. It is also accompanied by a huge strain that is attributed to repetitive poling and depoling originating due to the reversibility of the phase transition. The 25ST makes an attractive lead‐free candidate for stack actuators as it presents a high normalized d33* of ~600 pm/V at a low electric field of 4 kV/mm for frequencies ranging from 0.1 up to 100 Hz.

“…Improved poling of ceramics at MPB and facilitated domain wall displacement in ceramics add to this intrinsic mechanism. However, as shown by Jones et al (2007) and Hall et al (2005), internal stresses in ceramics, interactions among grains and domains, and local texture affect the overall intrinsic as well as extrinsic response of ceramics and should not be neglected.…”

This chapter discusses properties of lead-based piezoelectric materials, the most versatile and the most widely used piezoelectrics. Majority of these materials were discovered in 1950s and 1960s, and their properties and applications are described in classical textbooks, e.g. (Jaffe et al. 1971;Lines and Glass 1979). After giving essential background, this chapter will focus on recent developments. Lead titanate is discussed first, followed by modified lead titanate compositions. Lead zirconate titanate is then discussed in some details, focusing on mechanisms of hardening and softening and properties at morphotropic phase boundary. The subsequent sections discuss field-induced piezoelectric effect in relaxors, relaxor-ferroelectric ceramics, and crystals. Other lead-based materials and environmental issues are briefly discussed in the closing sections of the chapter. Lead Titanate (PbTiO 3 )Pure lead titanate, PbTiO 3 , is not commercially used as a piezoelectric material, but can be either modified or form solid solutions to obtain materials with excellent piezoelectric properties. Most of piezoelectrics presently exploited commercially are solid solutions based on lead titanate. In this section, the structure and basic properties of PbTiO 3 are presented.PbTiO 3 belongs to the perovskite family, ABO 3 . At room temperature, PbTiO 3 is ferroelectric with tetragonal C 1 4v − P4mm space group. Lead titanate undergoes a first-order phase transition at 493 • C into cubic O 1 4 − Pm3m paraelectric form. This phase transition was considered in the past to be a prototypic displacive phase transition (Lines and Glass 1979) but recent results have suggested that it exhibits mixed displacive and order-disorder character (Nelmes et al. 1990).

“…Recent time-resolved x-ray experiments on tetragonal phase, poled ceramic PZT illustrate that the effective d 333 piezoelectric coefficient was nearly zero suggesting negligible lattice distortion from an applied field. [6][7][8] When the field was applied at angles that are not aligned with the polarization, the effective d 333 coefficient increases to a maximum near 45 • and then begins to decrease as the angle between the applied field and polarization approach 90 • . The result suggests polarization rotation is the primary effect influencing deformation.…”

Electromechanical coupling in ferroelectric materials is extended to include the electric quadrupole. Internal lattice displacements are coupled to strain to calculate both the polarization and the quadrupole and to provide general methods to describe both acoustic and optical material behavior. Electromechanical coupling of a monodomain is first analyzed and followed by finite element phase field simulations of a 180 • domain wall. A comparison between explicit electrostrictive coupling and nonlinear geometric effects is given which illustrate that phenomenological electrostriction gives exactly the same electromechanical coupling as obtained from introducing an effective field within the electrostatic Lorentz force.
