Abstract :
The dielectric, piezoelectric, mechanical properties, and structure of the complex perovskite ceramics in the Bi(Zn1/2Zr1/2)O3-PbTiO3 system have been measured in the temperature range from 283 K to 900 K with the intention of utilizing them in electromechanical transducer applications. The effect of complex PbLi1/4Sb3/4O 3 (PLS) modifications on the mechanical quality factor and piezoelectric properties was investigated for several xBZZ-(1-x)PT compositions. Additions of PLS resulted in gradual lowering of mechanical quality factor. All the properties allow them to be used in broadband electroacoustic transducers, accelerometers, and vibration pickups operating over a wide temperature range
