摘要

在283 K ~ 900 K的温度范围内，测量了Bi(Zn/sub 1/2/Zr/sub 1/2/)O/sub 3/-PbTiO/sub 3/体系中复合钙钛矿陶瓷的介电、压电、力学性能和结构，以期将其应用于机电换能器中。研究了pbi /sub 1/4/Sb/sub 3/4/O/sub 3/ (PLS)复合改性对xBZZ-(1-x)PT复合材料力学品质因子和压电性能的影响。PLS的加入使机械品质因子逐渐降低。所有这些特性使它们能够用于宽温度范围内的宽带电声换能器、加速度计和振动拾取器。

Ferroelectric ceramics in the Bi(Zn/sub 1/2/Zr/sub 1/2/)O/sub 3/-PbTiO/sub 3/ system

The dielectric, piezoelectric, mechanical properties, and structure of the complex perovskite ceramics in the Bi(Zn/sub 1/2/Zr/sub 1/2/)O/sub 3/-PbTiO/sub 3/ 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 PbLi/sub 1/4/Sb/sub 3/4/O/sub 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.
