DIELECTRIC , 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 کاملEnhanced dielectric and piezoelectric properties of xBaZrO3-(12x)BaTiO3 ceramics
xBaZrO3-(1!x)BaTiO3 solid solutions (x 1⁄4 0, 0.04, 0.06, 0.08, 0.12, and 0.18) synthesized via conventional solid state reaction method exhibit piezoelectric coefficients comparable to those of “hard” PZT-8, PZT-4, and even “soft” PZT-5A. Doping also improves the poling efficiency of xBaZrO3-(1!x)BaTiO3 ceramics. Study of temperature dependence of the dielectric and piezoelectric properties re...
متن کاملLow-temperature sintering of MnO2-doped PZT–PZN Piezoelectric ceramics
The effect of MnO2 addition on the microstructural evolution and piezoelectric properties of low temperature sinterable PZT–PZN ceramics was investigated. When a small amount of MnO2 (≤0.5 wt% ) was added, the Mn ions were homogeneously dissolved in the PZT– PZN ceramics, leading to full densification at a temperature as low as 930 °C. However, the further addition of MnO2 hindered the densific...
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...
متن کاملCOMPARISON OF MECHANICAL AND ELECTRICAL PROPERTIES OF PIEZOELECTRIC COMPOSITES PZT/ZnO AND PZT/Al FABRICATED BY POWDER METALLURGY
Lead zirconate titanate (PZT) as a piezoelectric ceramic has been used widely in the fields of electronics, biomedical engineering, mechatronics and thermoelectric. Although, the electrical properties of PZT ceramics is a major considerable, but the mechanical properties such as fracture strength and toughness should be improved for many applications. In this study, lead monoxide, zirconium ...
