Preparation and Characterization of Lead-Free Piezoelectric Ceramics [PDF]

Key Engineering Materials, 2011
(K,Na)NbO3-based piezoelectric ceramics are promising candidates for practical applications of lead-free piezoelectric materials due to their excellent piezoelectric properties. In this paper, lead-free piezoelectric ceramics (K0.44Na0.52Li0.04)(Nb0.86Ta0.10Sb0.04)O3(KNL-NTS)were successfully fabricated by traditional ceramics processing.

Fe-Doped Barium Lanthanum Titanate as a Competitor to Other Lead- Free Piezoelectric Ceramics [PDF]

, 2022
Multiferroic solid solutions of Ba1−xLaxTi1−x/4O3 and iron (BLFT) were synthesized using the conventional mixed oxide method. The dependence of the piezoelectric coefficients on Fe content in BLFT ceramics was determined by the quasi-static and resonance

Lead-free piezoelectric ceramics: Alternatives for PZT? [PDF]

Journal of Electroceramics, 2007
Investigations in the development of lead-free piezoelectric ceramics have recently claimed comparable properties to the lead-based ferroelectric perovskites, represented by Pb(Zr,Ti)O3, or PZT. In this work, the scientific and technical impact of these materials is contrasted with the various families of “soft” and “hard” PZTs. On the scientific front,
