摘要

Piezoelectric and dielectric properties of (Li_xNa_(1-x))NbO_3 (LNN100x; x≤0.14) ceramics were investigated according to phase transition The highest electromechanical coupling factor, k_p, of 0.247 was obtained for LNN12 which has a composition with a morphotropic phase boundary at room temperature. On the other hand, the coupling factor of k_(33) with longitudinal mode was almost constant for all compositions of x. The dielectric constant, ε_τ, before poling treatment exhibited a thermal hysteresis near the Curie temperature, T_C, for all compositions. The depolarization temperature of LNN6 was higher than the T_C before poling treatment. In addition, the peak of free permittivity, ε_(33)~T, was shifted to higher temperature. It was considered that the phase transition was induced by the electric field during poling treatment.
