Effect of La on piezoelectric properties of Pb(Ni1/3Sb2/3)O3–Pb(ZrTi)O3 ferroelectric ceramics

Harvesting Power Through Random Vibrations of Aerospace Vehicles from Nanostructured La-Pb(Ni1/3Sb2/3) - PbZrTiO3 Ferroelectric Ceramics

“…Though 5 h milled powder show existence of perovskite phase, it also shows the existence of mixture of starting powders along with traces of PbTiO 3 29,30 and PbZrO 3 31 . Increasing the milling time to 10 h, mechanically activated solid state reaction is advanced largely, leading to formation of perovskite phase to greater extent indicated by rise in peak intensity of perovskite planes 7,22 and reduction in peaks for starting components. Further increasing the milling duration to 20 h and 30 h, improvement of solid state reaction for formation of La-PNS-PZT in perovskite phase was noticed.…”

“…Piezoelectric charge coefficient (d 33 ) was measured at 100 Hz using piezo d 33 Meter (PM 300 Piezo Test, UK). Piezoelectric voltage coefficient (g 33 ) and figure of merit for power harvesting (FoM ph ) were calculated using standard mathematical relations 5,7,22 . Temperature stability of dielectric constant was evaluated in the temperature range between -50 °C and +340 °C using dielectric analyser (Novatherm Quotro, Novocontrol GmbH).…”

“…The authors of the present work, have also investigated and reported a novelty of a lanthanum doped PNS-PZT compositions [La-PNS-PZT], at MPB of PZT and reported for various properties suitable for power harvesting 2,7 , underwater sensor 9 and actuator applications 7,27 during their earlier studies. All these studies were restricted to the compositional powders in micro-meter regime.…”

“…PZT based piezoceramics are electromechanical energy converters, are suitable for sensors, actuators [1][2][3][4] and power harvesting applications [5][6][7][8] in civil and defence sectors 9 . PZT compounds crystallize in ABO 3 type perovskite structure in which 'A' is a large divalent Pb 2+ cation occupies the corner of the unit cell.…”

Antimony Oxide-Doped 0.99Pb(Zr0.53Ti0.47)O3–0.01Bi(Y1−xSbx)O3 Piezoelectric Ceramics for Energy-Harvesting Applications

“…Among the various piezoelectric materials, lead zirconate titanate (PZT) based ceramic is one of the most widely used because of its fast electro-mechanical response, relatively low power requirements, high generative force, and inherent durability [3][4][5][6][7]. Extensive research and development of PZT-based ceramics have been conducted to find such piezoelectric materials [1,[7][8][9][10]. A variety of parameters is used to compare piezoelectric materials for energy-harvesting, such as electromechanical coupling factor, piezoelectric charge constant, output voltage, power density, energy-conversion efficiency, and cost and frequency of operation.…”
