Fine grains ceramics of PIN-PT, PIN-PMN-PT and PMN-PT systems Drift of the dielectric constant under high electric field

Résumé

Lead-based ferroelectric ceramics with (1-x)Pb(B1 B2)O3-xPbTiO3 formula have emerged as a group of promising materials for various applications like ultrasonic sonars or medical imaging transducers. (1-x)PMN-xPT, (1-x)PIN-xPT and ternary solutions xPIN-yPMN-zPT ceramics are synthesised using the solid state reaction method. Our objective is to achieve higher structural transition temperatures than those of PMN-PT ceramics with as good dielectric, piezoelectric and electromechanical properties. Ceramics capacitance and loss tangent are measured when the ac field of measurement increases up to E = 500 V/mm. Behaviours of these materials under ac field are related to their coercive field and Curie temperature. © 2006 Elsevier B.V. All rights reserved.
