Conclusions and Future Works High Curie temperature single crystal PYNT and BSPT have been grown using flux method Large Coercive field domain stability Ec10-30kVcm Promising piezoelectric and electromechanical properties in rhombohedral phase which expand the application temperature range to about 300 deg C d33800-2000pCN Tetragonal BSPT crystal has very low dielectric constant at room temperature which is candidate for the single-element transducer K300 Try to find new method to grow large rhombohedral phase BSPT and PYNT crystals, explore excellent properties of the new materials.
