Abstract

(1 - x)K_0.48Na_0.52Nb_0.98Sb _0.02O₃-xBi_0.5Na_0.5ZrO₃ lead-free piezoceramics were prepared by using the conventional solid-state method. In this material system, (Bi_0.5Na_0.5)²⁺ and Zr⁴⁺ can decrease the orthorhombic-tetragonal phase temperature and increase the rhombohedral-orthorhombic phase temperature. The rhombohedral-tetragonal phase coexistence is identified in the ceramics with the compositional range of 0.03 < x < 0.05. The ceramic with x = 0.04 has an enhanced piezoelectric behaviour of d₃₃ ∼ 257 pC N^-1 and k_p ∼ 41%, which is three times higher than that of a pure KNN ceramic. In addition, the enhanced stability of piezoelectric and ferroelectric properties is also observed in such a ceramic. These results show that such a new lead-free material system is a promising candidate for piezoelectric devices.
