摘要：

LiSbO3 doped and undoped 0.995 K0.5Na0.5NbO3-0.005BiFeO(3) piezoelectric ceramics with high properties have been fabricated in air by the conventional ceramic processing. By adding LiSbO3 to K0.5Na0.5NbO3-BiFeO3 ceramics, the dielectric and piezoelectric properties evidently increase. The doped ceramics exhibit good electrical properties. The enhanced piezoelectric properties of the ceramics should be attributed to optimum LiSbO3 substitution and better microstructure with high density. Results show that LiSbO3 doped K0.5Na0.5NbO3-BiFeO3 lead-free piezoelectric ceramics are a promising lead-free piezoelectric material for applications in different devices. (C) 2009 Elsevier B.V.
