摘要:Lead-free piezoelectric ceramics with the composition of (Na0.53K0.435Li0.035) Nb-0.94-xSbxTa0.06O3 (NKLNST) are synthesized by a conventional solid-state sintering process. An MPB-like region between orthorhombic and pseudocubic phases is found in this system. The density, piezoelectric and dielectric properties are enhanced greatly in this region. A composition (Na0.53K0.435Li0.035) (Nb0.86Sb0.08Ta0.06) O-3 is found to have excellent electrical properties: d(33) = 320 pC/ N, k(p) = 49% and k(t) = 43%, as well as relatively low loss, tan delta = 4.2%, and high relative density higher than 96%, which indicate that this ceramics is a promising lead-free piezoceramics replacing for lead zirconate titanate.
