The Effect of K+ Doping on the Ordered Micro-region, Dielectric and Electrostrictive Properties of 0.80Pb(Mg1/3Nb2/3)O3-0.20PbTiO3 Ceramics

使用二次合成法制备了不同钾含量的0.80Pb(Mg1/3Nb2/3)O3-0.20PbTiO3陶瓷,首先研究了掺钾对PMN基预烧粉体和陶瓷试样相组成的影响,在此基础上详细研究了掺钾对PMN基陶瓷有序微区、介电和电致伸缩性能的影响规律.掺钾对PMN基预烧粉体和陶瓷的相组成影响很小;理论计算和Raman散射光谱分析都表明掺钾使PMN基陶瓷的有序微区的尺寸稍微减小;掺钾也小幅度地减小了PMN基陶瓷的介电和电致伸缩性能,最后分析了掺钾降低介电和电致伸缩性能的原因.
