Electromechanical behaviour of PZT with real domain structure

Fatigue failure characteristics of lead zirconate titanate piezoelectric ceramics

“…Anteboth et al also observed the domain direction in the PZT ceramic using a scanning force microscope and detected different domain orientations. 24 Although several investigators have observed domain wall formation in PZT grains, there is no clear explanation for the relationship between the poling direction and the domain wall orientation. The creation of an aligned domain wall might be a result of: (i) an electric dipole moment and (ii) a high applied stress.…”

Multiferroic composites in nano–microscale with non-solid solution by Co-ferrite and (K0.5Na0.5)NbO3-based ferroelectric matrix

“…Although piezoelectric ceramic Pb(Zr,Ti)O 3 has higher piezoelectric coefficient than other piezoelectric materials [17,18], environmental issues, however, may ultimately require the replacement of these lead based materials [19]. 0.948(K 0.5 Na 0.5 )NbO 3 -0.052LiSbO 3 (KNN-LS5.2) lead-free ceramic is a promising candidate, which exhibits a high spontaneous polarization, a high dielectric constant and high piezoelectric coefficient with piezoelectric properties of k 33 ∼ 62% and d 33 ∼ 265 pC/N [18].…”

Harmonic electro-optic modulation using relaxor ferroelectric PLZT ceramics

“…The structural 9, 10 , dielectric 11,12,13 , electro-mechanical 14,15 and optical 16,17 properties of PLZT have been widely studied in recent years, and many peculiarities 18,19 were observed in their behavior. The electro-optic modulation 20,21,22,23 , as well as the second harmonic generation 24,25 of light in PLZT have been previously studied for use in lasers, spatial light modulators and other optical applications.…”
