Effects of uniaxial stress on dielectric properties lead magnesium niobate-lead zirconate titanate ceramics

Effects of uniaxial stress on the dielectric properties of ceramics in lead magnesium niobate-lead zirconate titanate (PMN-PZT) system are investigated. The ceramics with a formula (x)Pb(Mg1/3Nb2/3)O3-(1 - x)Pb(Zr0.52Ti0.48)O3 or (x)PMN-(1 - x)PZT when x = 0.0, 0.1, 0.3, 0.5, 0.7, 0.9, and 1.0 are p...

Phase formation behaviour and microstructural features of these ceramics are studied by x-ray diffraction and scanning electron microscopy methods, respectively. The dielectric properties under the uniaxial stress of the PMN-PZT ceramics are observed at stress levels up to 5 MPa using a uniaxial compressometer. It is found that with increasing applied stress the dielectric constant of the PZT-rich compositions increases slightly, while that of the PMN-rich compositions decreases. On the other hand, the dielectric loss tangent for most of the compositions first rises and then drops with increasing applied stress. 2014-08-30T03:23:44Z 2014-08-30T03:23:44Z 2003 Article 00223727 10.1088/0022-3727/36/13/329 JPAPB http://www.scopus.com/inward/record.url?eid=2-s2.0-0037767547&partnerID=40&md5=b2714f3f365b01fc73c7b5767dd79d5c http://cmuir.cmu.ac.th/handle/6653943832/6019 English
