A synergistic approach to attain high piezoelectricity in a Pb(Ni, Nb)O₃–Pb(Lu, Nb)O₃–PbTiO₃ system

Abstract

Modern electronic devices are highly demanded for high-performance piezoelectric materials. Herein, Pb(Ni, Nb)O3-Pb(Lu, Nb)O3-PbTiO3 piezoelectric ceramics are investigated, among which 0.52PNN-0.16PLN-0.32PT ceramic shows the best performance (d33 = 850 pC/N,...

Structural evolution of a high-temperature piezoelectric Pb(In1/2Nb1/2)O3–PbTiO3 ceramic under an in situ electric field

“…1–4 For example, various ternary systems with high piezoelectricity ( d 33 > 600 pC N −1 ) have been developed based on the Pb(Mg 1/3 Nb 2/3 )O 3 –PbTiO 3 (PMN–PT) 5–8 and Pb(Ni 1/3 Nb 2/3 )O 3 –PbTiO 3 (PNN–PT) binary relaxor ferroelectrics. 9–14 However, due to the relatively low Curie temperature ( T C ) of PMN–PT and PNN–PT, the temperature stability of the corresponding constructed ternary systems is reduced, which limits their application at elevated temperatures. 5–12 In contrast, the T C of the Pb(In 1/2 Nb 1/2 )O 3 –PbTiO 3 (PIN–PT) binary relaxor ferroelectric is higher than 250 °C, making it highly promising for constructing high-temperature piezoelectric systems.…”
