Dielectric and piezoelectric properties of the mechanochemically prepared PZT ceramics
(Kluwer Academic Publ, 2004-08-01)
Mechanochemical synthesis was applied to obtain nanocrystalline powders of composition Pb(Zr0.52Ti0.48)O-3 (PZT). Milling was performed in a planetary ball mill using vials and balls made of zirconia or steel-in order to ...

Exploring new methodologies for the identification of the morphotropic phase boundary region in the (BiNa)TiO3-BaTiO3 lead free piezoceramics: Confocal Raman Microscopy
(Elsevier Science Sa, 2018-03-28)
On ferroelectrics materials, the piezoelectric activity is enhanced near the so-called morphotropic phase boundary (MPB) separating the rhombohedral and tetragonal phases in the binary phase diagram. Here, we report the ...
Low-cost piezoelectric transducer for ceramic grinding monitoring
(2019-09-01)
This paper presents a performance assessment of the low-cost thin-disk piezoelectric diaphragm (PZT) for the surface integrity monitoring in the grinding operation. PZT diaphragms are flexible, low-cost, and smart devices, ...
Phase structure and piezoelectric properties of Ca- and Ba-doped K 1/2Na1/2NbO3 lead-free ceramics
(Elsevier, 2013-05)
Piezoelectric lead-free ceramics, K1/2Na1/2NbO 3 (KNN) modified with alkaline-earth (AE) Ca2+ and Ba 2+, have been prepared by the conventional solid-state reaction method. The effect of doping level on sinterability and ...

Piezo and Dielectric Properties of PHB-PZT Composite
(John Wiley & Sons IncHobokenEUA, 2009)
Lead zirconate titanate/polyurethane (PZT/PU) composite for acoustic emission sensors
(2001-01-01)
Piezoelectric composite, made from ferroelectric ceramic lead zirconate titanate (PZT) and vegetable based polyurethane (PU) polymer, was doped with a semiconductor filler, graphite. The resulting composite (PZT/C/PU) with ...
