0.852[Bi1/2(Na1−x Li x )1/2]TiO3–0.110(Bi1/2K1/2)TiO3–0.038Ba0.85Ca0.15Ti0.90Zr0.10O3 (BNLT–BKT–BCTZ-x) new ternary piezoelectric ceramics were fabricated by the conventional solid-state method, and their piezoelectric properties as a function of the Li content were mainly investigated. A stable solid solution with a single perovskite structure has been formed, and the depolarization temperature (T d) of these ceramics was identified by using the temperature dependence of the dielectric loss. The T d value of these ceramics gradually decreases, while the T m value increases with increasing the Li content. The dielectric constant increases and the dielectric loss decreases with increasing the Li content, and an enhanced piezoelectric behavior of d 33∼223 pC/N and k p∼35.2 % has been demonstrated in these ceramics with x=0.06.
