摘要
通过电滞回线测试,探讨了xPb(Mn1/3Sb2/3)0.05(Zr1/2Ti1/2)0.95O3(1-x)Pb(Zn1/3Nb2/3)0.28(Zr1/2Ti1/2)0.72O3[xPMnS-(1-x)PZN]陶瓷的铁电性能及铁电相变特性。同时研究了Ba2+取代Pb2+对材料铁电性能的影响。结果表明:三方相含量较高的0.2PMnS-0.8PZN陶瓷具有较高的矫顽场和较大的剩余极化强度;四方相含量较高的0.5PMnS-0.5PZN和0.6PMnS-0.4PZN陶瓷具有较低的矫顽场和较小的剩余极化强度,Ba2+取代使三方相含量增加,铁电性能明显提高。
Through testing of the hysteresis loop, the ferroele.ctric properties and ferroelectric phase transition of xPb（Mn1/3Sb2/3）0.05（Zr1/2Ti1/2）0.95O3（1-x）Pb（Zn1/3Nb2/3）0.28（Z1/2Ti1/2）0.72O3 [xPMnS-（1-x）PZN] ceramics were cletermined. The effect of the substitution of Ba^2＋ for Pb^2＋ on .the ferroelectric properties of the material was also studied, The results show that 0.2PMnS-0.8PZN ceramic with high rhombohedral phase content has a higher coercive field and a larger remnant polarization, while 0.5PMnS-0.5PZN and 0.6PMnS-0.4PZN ceramics with high tetragonal phase content have a low.er coercive field and a smaller remnant polarization. The substitution of Ba^2＋ for pb^2＋ can increase the co.ntent of the rhombohedral phase and thus improve the f crroelectric properties of the material.
