| 摘 要： | 在烧结温度为1020℃下,采用固相二步合成法制备了Pb(Ni1/3Nb2/3)0.05(Mn1/3Nb2/3)0.04(Mn1/3Sb2/3)0.01(Zr1/2Ti1/2)0.9O3(PMNNS)压电陶瓷,研究了加入不同掺杂量的SiO2对陶瓷的结构与机电性能的影响。结果表明:加入SiO2可以明显地降低烧结温度;而且当SiO2的掺杂量为0.1%时,陶瓷的性能最佳,其性能如下:d33=331 pC/N,tanδ=0.0041,kp=0.62,Qm=1326,εr=917。

| Abstract: | Pb(Ni1/3Nb2/3)0.05(Mn1/3Nb2/3)0.04(Mn1/3Sb2/3)0.01(Zr1/2Ti1/2)0.9O3(PMNNS) were prepared using the two-step solid phase synthesis method at the sintering temperature of 1020 ℃.The effects of different amount of SiO2-doped on crystallographic phase and electromechanical properties were investigated.The results showed that SiO2 addition could significantly reduced the sintering temperature,and when the amount of SiO2 doped was 0.1%,the optimized properties were obtained,which are listed as follows:d33=331 pC/N,tanδ=0.0041,kp=0.62,Qm=1326,εr =917. |
