Abstract :
Dense lead-free binary system piezoelectric
ceramics (1 - x)[Bi0.5(Na0.7K0.25Li0.05)0.5]TiO3-xBa(Ti0.95
Zr0.05)O3 (BNKLT–BZT) were prepared by a two-step sintering
process. A phase transition from rhombohedral to
tetragonal was observed with increasing BZT fraction in the
range x = 0.06–0.1 and the morphotropic phase boundary
(MPB) between rhombohedral and tetragonal appears in this
range. Ceramics containing 10 mol% BZT with tetragonal
phase near the MPB region has the maximum piezoelectric
constant d33(151pC/N).
