Piezoelectric ceramics in the ternary system (0.8−x)PbSnO3–0.2Pb(Mg1/3Nb2/3)O3–xPbTiO3 (PSn–PMN–PT, x = 0.42–0.47) were synthesized. Morphotropic phase boundary (MPB) compositions, located at ~PT = 0.43–0.45 were confirmed by X‐ray diffraction, dielectric, piezoelectric, and ferroelectric properties. The coercive field EC, internal bias field Ei, and mechanical quality factor Qm were found to increase with increasing PT content, indicative of piezoelectric “hardening” characteristics, while the optimum dielectric and piezoelectric properties were achieved for the MPB composition 0.36PSn–0.2PMN–0.44PT, with dielectric permittivity εr, piezoelectric coefficient d33, and planar electromechanical coupling kp being on the order of 2930, 510 pC/N and 55%, respectively. In addition, the aging behavior of the piezoelectric ceramics was studied, with aging rate of d33 ~−6%, kp ~−2%, εr ~−7% per decade, respectively, similar to commercial PZT4 ceramics.

“…. After 700 h, d 33 , k p and ε r were found to decrease by about 19%, 6%, and 24%, respectively, which is mainly associated with the relaxation of the domain walls . The average calculated aging rate for d 33 , k p and ε r is about −6%, −2%, −7% per decade, respectively, similar to PZT4 ceramics…”

“…7. With increasing the sintering temperature, k p , k t , Q m and d 33 values of specimens increase and then reach the saturation at sintering temperatures 980-1020 • C. A suitable amount of ZnO can lower the sintering temperature and increase the grain size, resulting in easy domain wall motion [17].…”

“…Ahn et al showed that ZnO was effective in improving the piezoelectric properties [15]. Yoon et al showed that ZnO could enhance the piezoelectric voltage output coefficient (g 33 ) and piezoelectric charge constant (d 33 ) [16], Wang et al reported that the ZnO nanowhisker could greatly improve the piezoelectric properties, mechanical strength and aging rate of PZT ceramics [17], and Zhao found the similar results from nano ZnO doping into the PZT thick-film by a hybrid sol-gel route [18]. Wongmaneerung et al also showed that the suitable addition of ZnO nanowhiskers into PT ceramics could enhance the densification, mechanical and dielectric properties [19].…”

“…and , respectively. With the addition of Al 2 O 3 , the properties of PST–PMN, including the piezoelectric coefficient d 33 , planar electromechanical coupling k p and mechanical quality factor Q m , were found to decrease, which is mainly attributed to the presence of pyrochlore phase .

The PbSnO 3 -PbTiO 3 -Pb(Mg 1/3 Nb 2/3 )O 3 (PST-PMN) ternary system with morphotropic phase-boundary (MPB) compositions were fabricated using a two-step columbite precursor method. The effects of Al 2 O 3 and MnO 2 addition on the dielectric, piezoelectric, and ferroelectric properties of PST-PMN were investigated. MnO 2 acted as an acceptor dopant and induced a ''hardening'' effect in PST-PMN, with decreased piezoelectric coefficients d 33 and increased mechanical quality factors Q m , while the addition of Al 2 O 3 led to the significant decrease of piezoelectric properties, attributed to the second phase. Of particular interest is the fact that the Mn-doped PST-PMN exhibited excellent properties when the doping level was in the range of 0.2-0.5 wt%, with piezoelectric d 33 , planar electromechanical coupling k p , dielectric permittivity e r , Q m , remnant polarization P r and coercive field E C being on the order of $510 pC N À1 , $57%, 3120-3500, 530-600, 27-30 mC cm À2 , and $8 kV cm À1 , respectively, showing advantages over commercial PZT4-type ceramics, which are promising for high-power electromechanical applications.
