Characterization of High Curie Temperature Piezocrystals: doped Pb(Yb1/2Nb1/2)O3-PbTiO3 and BiScO3-PbTiO3

Abstract

Conclusions and Future Works: "High Curie temperature single crystal PYNT and BSPT have been grown using flux method "Large Coercive field domain stability (Ec^10-30kV/cm) "Promising piezoelectric and electromechanical properties in rhombohedral phase which expand the application temperature range to about 300 deg C (d33^800-2000pC/N) "Tetragonal BSPT crystal has very low dielectric constant at room temperature which is candidate for the single-element transducer (K^300) * Try to find new method to grow large rhombohedral phase BSPT and PYNT crystals, explore excellent properties of the new materials.
