| 摘 要： | 通过对晶体结构与压电、介电性能测试,探讨了Fe_2O_3掺杂对PMnS-PZN-PZT陶瓷压电性能的影响.结果表明,PMnS-PZN-PZT陶瓷结构位于三方、四方相共存的MPB区间,Fe_2O_3掺杂导致晶体三方、四方相结构含量发生变化.当Fe_2O_3掺杂含量为0.45 wt;时,晶体结构位于准同型相区间偏四方相结构的位置,压电与介电性能达到最佳:tanδ=0.12;,d_(33)=356 pC · N~(-1),k_p=0.60,Q_m=745,在230 ℃以下的温度范围具有很好的频率温度稳定性.

| Abstract: | With the test of structure and piezoelectric and dielectric properties,the effects of Fe2O3 doping on the piezoelectric properties of PMnS-PZN-PZT ceramics were studied.The results show that the rhombohedral and tetragonal phase coexisted in MPB and the content of rhombohedral and tetragonal phase structure of this material was changed because of Fe2O3 doping.When the content of Fe2O3 is 0.45 wt%,the MPB was obtained and the sturcture leans to tetragonal phase,which lead to the excellent piezoelectric and d... |
