La 2 O 3 (0-0.8 wt.%)-doped (Bi 0.5 Na 0.5 ) 0.94 Ba 0.06 TiO 3 (abbreviated as BNBT6) lead-free piezoelectric ceramics were synthesized by conventional solid-state reaction. The influences of La 2 O 3 on the microstructure, the dielectric, ferroelectric and piezoelectric properties of the composite
The piezoelectric ceramics Pb(Ni 1/2 W 1/2 )O 3 -Pb(Mn 1/3 Sb 2/3 )O 3 -Pb(Ti 1/2 Zr 1/2 )O 3 -x wt% MnO 2 (abbreviated as PNW-PMS-PZT) were prepared by traditional ceramics process. The phase structure of ceramics sintered at 1150 β’ C was analyzed. Results show that the pure perovskite phase is in
Ferroelectric materials with high Curie temperature (higher than 300 β’ C) are highly desirable to construct transducers for high-temperature piezoelectric applications. Among the ferroelectric materials, PbNb 2 O 6 (PN) is considered to be one of the most promising materials. However, the fabricati
