Lead zirconate titanate ceramics

5 PZr is the trade name of the lead zirconate titanate piezoelectric ceramics of one of its largest producer, Vcmiiron. It is also commonly used in the scientific literature as a standard acronym. [Pg.217]

The crystallographic and piezoelectric properties of the ceramics depend dramatically on composition. As shown in Fig. 9.4, the zirconate-rich phase is rhombohedral, and the titanate-rich phase is tetragonal. Near the morphotrophic phase boundary, the piezoelectric coefficient reaches its maximum. Various commercial PZT ceramics are made from a solid solution with a zirconate-titanate ratio near this point, plus a few percent of various additives to fine tune the properties for different applications. [Pg.218]

In addition to the parameters discussed in the previous section, that is, the piezoelectric coefficients dsi, d3i, and the velocity of sound, c, there are several other parameters that are important for applications in STM. [Pg.218]

As a ferroelectric material, each piezoelectric ceramic is characterized by a Curie point or Curie temperature, T (Jaffe et al., 1971). Above this temperature, the ferroclcctricity is lost. An irreversible degradation of the [Pg.218]

While designing or using STM at low or high temperatures, the variation of piezoelectric coefficients with temperature has to be considered seriously. The variation differs for different PZT materials. Fig. 9.5 shows measured variations of d-i for several commonly used PZT materials with temperature. [Pg.219]
