| 摘 要： | 以Bi3TiNbO9和TiO2为原料，采用固相法合成Bi3TiNbO9（BTN）压电陶瓷．用X线衍射仪和电子显微镜等对陶瓷样品进行分析．实验结果表明，采用固相法可在较低烧结温度下制备出单相的BTN陶瓷．探讨不同工艺参数对BTN压电陶瓷的压电、介电性能的影响．实验发现，较高的成型压强可以制得致密且均匀的BTN陶瓷．再结晶可以使晶粒生长均匀，且能够承受较高的极化场强．在8kV／mm场强下极化的BTN陶瓷的压电常数d33为5．6pC／N．

| Abstract: | Ceramic samples with the composition of Bi3TiNbO9（BTN） were prepared by solidstate reaction method and using Bi203 ,TiO2 and Nb205 as start materials. The samples were analyzed using X-ray diffraction and scan electron microscopy. It was found that BTN ceramics could be fabricated at lower sintering temperature and the different process conditions had the important influence on their piezoelectric and dielectric properties. The dense and uniform BTN ceramics could be obtained by isostatic pressure, according to the experiment. The recrystallization could make the ceramic grains grow uniformly and withstand higher polarization field. The d33 of BTN ceramics poled by 8 kV/mm was about 5.6 pC/N. |
