چکیده
Solid solutions of BiFeO 3 and BaTiO are promising lead-free piezoelectric materials, especially around the morphotropic phase boundary at 0.67BiFeO -0.33BaTiO . Still, these materials challenged by instability limited understanding processing-properties relationship. Here, we investigate mechanochemical activation use as seed particles for phase. Contrary to expectations from seeding in lead-based perovskites, seeds do not promote perovskite neither during nor subsequent sintering, but cause an inhomogeneous structure with remnant This results ceramics weaker low-field response than that unseeded route, higher field-induced strain, even up 150 °C. Both routes produce high density without significant secondary phases visible X-ray diffraction. demonstrates advantage possibility tailor through processing route.

Non-linear Properties of Piezoelectric Ceramics
Sensors and actuators based on piezoelectric ceramics are finding an increasingly large variety of applications under a very wide range of environmental conditions and applied signals. Some actuator applications require the piezoelectric materials to support large mechanical loads and produce high strain output. In order to accomplish this requirement of higher strains, large electric fields mu...
متن کاملCharacterisation of Piezoelectric Ceramics
The IEEE standard on piezoelectricity recommends methods to determine the coefficients of piezoelectric ceramics and the sizes of the samples to be used. A method to determine the difference between the actual coefficients and the coefficients determined using the IEEE standard is presented. The difference or error for samples of various shapes and sizes is presented. These errors and manufactu...
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 کاملPiezoelectric Ceramics Characterization
This review explores piezoelectric ceramics analysis and characterization. The focus is on polycrystalline ceramics; therefore, single crystals, polymeric materials and organic/inorganic composites are outside the scope of this review. To thoroughly grasp the behavior of a piezoelectric polycrystalline ceramic, a basic understanding of the ceramic itself should not be overlooked. To this end, w...
