Pre-stressed curved actuators consist of a piezoelectric ceramic (lead zirconate titanate or PZT) sandwiched between various substrates and other top layers. The substrates used in this study are stainless steel, and fiberglass. The top layers are made up of aluminum and carbon. Due to their enhanced strain capabilities, these pre-stressed piezoelectric devices are of interest in a variety of a...

Polycrystalline ceramics of bismuth layered structure of (Bi2O3)(BaxFe1-xO3) (0.2x0.8, x is in step of 0.2) have been prepared by conventional solid-state reaction method to study its modified dielectric and electrical properties. X-ray diffraction technique is used on the powdered samples for physical characterization and an average grain size of 16 – 21 nm was obtained. The XRD analysis rev...

Experimental results on photoemission by ferroelectric ceramic disks, with a possible interpretation, are presented. Two types of lead zirconate titanate lanthanum doped, PLZT, ceramics have been used for tests. 25 ps light pulses of 532 and 355 nm were used for excitation. The intensity ranged within the interval 0.1-3 GW/cm. The upper limit of the intensity was established by the damage thres...

Research and development of lead-free piezoelectric materials are still the hottest topics in the field of piezoelectricity. One of the most promising lead-free family of compounds to replace lead zirconate-titanate for actuators is that of Bi0.50Na0.50TiO₃ (BNT) based solid solutions. The pseudo-binary (1 - x)Bi0.50Na0.50TiO₃-xBa1 - yCayTiO₃ system has been proposed for high temperature capaci...

Perovskite-type Ba0.9Sr0.1Ti0.9Sn0.1O3(BSTSn) ceramic was synthesized by the sol-gel method.

Barium titanate, BaTiO3, nanoparticles (NPs) have been widely used as a ferroelectric/piezoelectric/ pyroelectric material in the electronic-optical ceramic industry. However, stability of BaTiO3 NP suspension is matter concern for their advanced applications wet-ceramic manufacturing, imaging, and electrorheological fluids. In this study, we investigated effect three different surfactants (sod...

Electric field-induced phase transitions were investigated in (111), (110), and (100) thin platelets of relaxor ferroelectric Pb(Mg1∕3Nb2∕3)O3 single crystals with electric fields applied along the ⟨111⟩, ⟨110⟩, and ⟨100⟩ directions, respectively. Temperature dependences of complex dielectric permittivity, pyroelectric current and dielectric hysteresis loops were investigated. Electric field-te...
