Effects of Zr/Ti ratio on structural, dielectric and piezoelectric properties of Mn- and (Mn, F)-doped lead zirconate titanate ceramics

Piezomechanics in PZT Stack Actuators for Cryogenic Fuel Injectors

“…The simulation result reasonably agrees with the experimental data. It is noted that at room temperature, the MPB is located at about X = 0.44, and that there is an apparent shift of about 13 mol% in the MPB location on cooling to 0 K. In the work of Boucher et al (2006), the piezoelectric coefficient d333 of PZT (Mn-doped) presented a significant decrease (about 85 %) due to a shift of 12 mol% of Zr at room temperature. Thus, from the consideration of Fig.…”

PZT ceramics prepared through a combined method of B-site precursor and wet mechanically activated calcinate in a planetary ball mill

“…It is known that PbO evaporates during sintering process at high temperatures from PZT phase, which causes degradation of ferroelectric and piezoelectric properties as a result of the formation of nonstoichiometric perovskite phase. Furthermore, PZT ceramics with higher Zr:Ti ratios have some difficulties in densification, leading to a lower performance [5]. A great deal of effort has been made during the last decades for enhancing the activity of PZT calcinate, while retaining proper ferroelectric and piezoelectric properties.…”

Effect of Mn2O3 addition on the microstructure and electrical properties of lead-free (Na0.5K0.5)NbO3-Ba(Sn0.02Ti0.98)O3 ceramics

“…Adding Mn is an often-adopted strategy to tailor the electrical properties of PZT-based piezoelectric ceramics. 17) Despite of these investigations, the role of Mn on the structure and electrical properties of NKN-based ceramics remains somewhat ambiguous. Therefore, further investigation on this subject is necessary.…”
