Abstract

Lead-free piezoelectric single crystal of [Bi_0.5(Na _1-xK_x)_0.5]TiO₃ (BNTKx) with size of 10×10×5 mm³ has been successfully grown by the self-flux method. The temperature dependence of dielectric constant was measured and the peak temperature of dielectric constant was found to be 45° higher than that of pure (Bi_0.5Na_0.5)TiO₃ crystal. X-ray diffraction pattern indicated that the BNTK50 crystal is tetragonal (symmetry group 4 mm) with a=b=0.3917nm and c=0.4011nm, respectively. Differential scanning calorimetry showed that the crystal was congruent melting during growth. Superior piezoelectric and electromechanical properties were found in these lead-free crystals.
