Ferroelectric effects in PZT
First-principles calculations are performed to investigate alloying and fer-roelectric effects in lead zirconate titanate (PZT) with high Ti composition. We find that the main effect of alloying in the paraelectric phase of PZT is the existence of two sets of B–O bonds, i.e., shorter Ti–O bonds vs. longer Zr–O bonds. On the other hand, ferroelectricity leads to the formation of very short coval...
متن کاملDielectric Properties and Morphology of Ferroelectric Ceramic-Polymer Composite Films
Dielectric constant and morphology of BaTiO3-polymer composite films were studied as a function of the filler concentration. The morphology of the films was examined using laser scanning confocal microscopy, which is capable to measure small particle distributions in more details than conventional microscopy. The thin-slice images allowed us to visualize the micronsize particles and the polymer...
متن کاملHigh frequency dielectric relaxation in polymers filled with ferroelectric ceramics
We investigated the dielectric relaxation process in high-dielectric constant polymer composite films filled with barium titanate particles. In order to extend the dielectric measurements to the microwave range, we employed a new broadband measurement technique where a thin film capacitance terminating a coaxial waveguide is treated as a transmission line. The complex permittivity, measured at ...
متن کاملDIELECTRIC , FERROELECTRIC AND PIEZOELECTRIC PROPERTIES OF La 3 + SUBSTIUTED PZT CERAMICS
Lanthanum substituted lead zirconate titanate (PLZT) nanocrystallite with stichometry formula Pb0.90La0.10 (Zr0.52Ti0.48) O3 have been synthesized by sol gel process. The effect of nanocrystallite on dielectric, ferroelectric and piezoelectric properties of La substituted PZT was studied. The average crystallite size of the PLZT powder was 21nm.Variation of dielectric constant with temperature ...
متن کاملEffects of microwave heating on dielectric and piezoelectric properties of PZT ceramic tapes
Commercial lead zirconate titanate (PZT) perovskite powders were used to fabricate ceramic tape and then sintered by microwave and conventional methods. Both dielectric and piezoelectric properties of PZT ceramic tapes were studied in terms of sintering process. X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM) show the PZT perovskite phase with smaller grain size and dens...
