| 摘 要： | 以硫铝酸盐水泥为基体, 铌镁锆钛酸铅(PMN) 陶瓷颗粒为功能体制备了水泥基压电复合材料。重点讨论了复合材料的介电性能和压电性能。结果表明: 水泥基压电复合材料的介电温谱在- 30 ℃～150 ℃范围内较平坦, 表现出优良的介电温度稳定性, 而介电损耗随着温度的升高而增加; 水泥基压电复合材料的压电应变常数和介电常数均随着PMN 含量的增加而增大。

| Abstract: | 0-3 cement based piezoelect ric composites were fabricated by compressing technique using PMN andsulphoaluminate cement as raw materials. The piezoelect ric and dielect ric properties of the composites were investigated. The result s indicate that the dielect ric constant s of the composites are almost constant over the temperatureranges between - 30 ℃and 150 ℃, which exhibit s good dielect ric-temperature stability. But dielect ric dissipation increases as temperature increases. With increasing PMN content , the piezoelect ric and dielect ric properties of thecomposites increase. The bet ter performances of the composites are exhibited when PZT content exceeds 70 %. |
