Compositional Design of Dielectric, Ferroelectric and Piezoelectric Properties of (K, Na)NbO3 and (Ba, Na)(Ti, Nb)O-3 Based Ceramics Prepared by Different Sintering Routes
(Mdpi Ag, 2016)
Lead free piezoelectric materials are being intensively investigated in order to substitute lead based ones, commonly used in many different applications. Among the most promising lead-free materials are those with modified ...
Influence of zirconium addition on final properties of K0.5Na0.5NbO3-based ceramics
(Springer, 2013-11-08)
Microstructure, electrical and dielectric properties of K1/2Na1/2NbO3 (KNN) modified with ZrO2 were investigated. Powders were obtained by a conventional solid-state method. In this way, samples doped with 0.2 mol% of ZrO2 ...
Rietveld analyses and piezoelectric properties of niobium doped bismuth titanate systems
(2010-08-01)
Bi 4Ti 3- xNbxO 12 (BITNb) samples, with × ranging from 0 to 0.40 were obtained using a polymeric precursor solution. Rietveld analyses confirmed that the powders crystallize in an orthorhombic structure free of secondary ...

The resonance frequencies on mechanically pre-stressed ultrasonic piezotransducers
(Elsevier Science BvAmsterdamHolanda, 2001)
Piezoelectric effect in composite polyurethane - Ferroelectric ceramics
(Wiley-Blackwell, 1999-03-16)
Flexible and free-standing films of piezoelectric composites made up of lead zirconate titanate (PZT) ceramic powder dispersed in a castor oil-based polyurethane (PU) matrix were obtained by spin coating and characterised ...
