Abstract

To realize the enhancement in piezoelectric activities, the composition-induced phase boundaries in (1-y)(K_0.40Na_0.60)_0.985Li_0.015(Nb_1-xSb_x)O₃-yBi_0.5Na_0.5ZrO₃ lead-free ceramics were designed and fabricated by the conventional solid-state method. We presented the evolutions of their phase structure, microstructure, and electrical properties with the change of Sb⁵⁺ and Bi_0.5Na_0.5ZrO₃ contents. A rhombohedral-tetragonal phase boundary was successfully built in the composition region of 0.04 ≤ x ≤ 0.09 (y = 0.025) and 0.025 ≤ y ≤ 0.035 (x = 0.06), and then the desirable piezoelectric coefficients and bipolar strains (e.g., d₃₃∼390 pC/N, k_p∼0.45, S_max∼0.2%, and T_C∼250 °C) were simultaneously induced. We think that this may provide a direction of designing high-performance (K,Na)NbO₃-based ceramics.
