Abstract

Several new systems of Bi0.5Na0.5TiO3-based lead-free piezoelectric ceramics were proposed based on the design of the multiple complex in the A-site of ABO3 compounds. These ceramics were prepared by conventional ceramic techniques. The comparison of the piezo- and ferroelectric properties of these ceramics with those of the best properties of the Bi0.5Na0.5TiO3-based lead-free piezoelectric ceramics published recently shows that these ceramics of the new systems have better ferroelectric and piezoelectric performance, and better temperature characteristic of the properties. Among these materials, Bi0.5(Na1−xy K x Li y )0.5TiO3 possesses higher piezoelectric constant (d 33 = 230.8 pC/N), higher electromechanical couple factor (k p = 0.41), larger remanent polarization (P r = 40 μC/cm2) and a better PE hysteresis loop below 200 °C. Practical devices such as ceramic middle frequency filters and buzzers have been made by using these lead-free piezoelectric ceramics.
