Description

As demonstrated in [1], electrical properties of piezoelectric ceramics based on lead zirconate-titanate (PZT) can be improved by consolidation of previously synthesized nanocrystalline PZT powder into compact nanostructured ceramic bodies. In this dataset, to assess possible benefits of nanostructured PZT piezoceramics, their dielectric and piezoelectric properties (Table 1) are compared with those of a series of PZT materials sintered by traditional solid-state technology (Table 2). This series includes modified materials doped with ferroelectrically “soft” and “hard” complex oxide additives (AA´)(BB´B´´)O3 for various commercial applications. In the formula A = Sr, Ba, Li, La, Ce, Bi; B = Mn, Ge, Zn, Ni, Cd, Nb, W, Al, Fe. An example of “soft” additive is Bi(Ni1/3W1/3)O3, while ZnBi2/3Mn1/2O3 is an example of “hard” additive. The size of nanocrystallites was determined as the dimension of coherent scattering regions (CSR) from X-ray diffraction (Table 1). Nanosized crystallites separated with low-angle boundaries assemble into larger microsized grains divided between themselves by high-angle boundaries. The size of these grains dgr (Table 1) was determined by scanning electron microscopy. [1] V.V. Prisedskii, V.M. Pogibko, V.S.
