摘 要：<正>The structure of piezoelectric ceramic in Pb[(Zn1/3Nb2/3(Sn1/2Nb2/3]（Zr,Ti）O3 system is studiedthrough XRD and TEM analysis.The effects of substitutionof Ba2+, Sr2+.for Pb2+and small amount of dopants such asMnO2 and Sb2O3 on the structure are investigated.The dif-ference between unpolarized and polarized XRD patternsand the structure of ferroelectric domains is emphaticallystudied.The result shows that the samples are of the tetrago-nal pertovskite-type structure.The dopants change the tetrago-nallty of samples and grain size but have no effect on thecrystal phase.The effects of polarizing on the structure canbe proved from the deformation of unit cell in microscopicstate and rotation of 90°ferroelectric domains in microscopicstate.
