Crystal Growth and Ferroelectric Properties in Bi0.5Na0.5TiO3–BaTiO3 Crystals
0.999Bi0.5Na0.5TiO3-0.001BaTiO3 (BNT-0.1%BT) single crystals with a maximum size of 1×1×1 mm3 were successfully grown by a flux method using BNT-6%BT powder and Bi2O3 as a flux. The crystals showed a remanent polarization of 33 μC/cm2 and coercive electric field of 40 kV/cm along Cubic. Electric-field induced strain measurements along Cubic revealed an effective piezoelectric strain constant d33 * of 80 pm/V.
