Gigantic electro-chemo-mechanical properties of nanostructured praseodymium doped ceria
Abstract
Some oxygen defective fluorites are non-Newnham electrostrictors, <em>i.e.</em>,the electromechanical response does not depend on their dielectricproperties. Here, we show gigantic electrostriction in nanocrystalline25 mol% praseodymium doped ceria (PCO) bulk ceramics. The material wasfabricated with a field-assisted spark plasma sintering (SPS) processfrom high-purity nanoscale PCO powders (<20 nm). The SPS processconsolidates the powders into a single-phase, highly dense material witha homogeneous microstructure and large grain boundary extension.Various thermally and chemically stable ionic defects are incorporatedinto the nanostructure, leading to superior electrical conductivity. Thematerial shows an electrostriction strain coefficient (<em>M</em><sub>33</sub>) of ∼10<sup>−16</sup> m<sup>2</sup> V<sup>−2</sup>at frequencies below 100 Hz at room temperature. Such performance iscomparable and even superior to Newnham's electrostrictors, such asferroelectric ceramics and polymeric actuators. Comparative analysiswith polycrystals suggests that nanostructured PCO possesseselectromechanically active nanodomains of Pr<sup>3+</sup>–V<sub>O</sub> pairs. Such results are unexpected and open novel insights on non-Newnham electrostrictors.
