Abstract

CuO-added 0.96(Na_0.5K_0.5)(Nb_1- _xSb_x)O₃-0.04SrTiO₃ ceramics sintered at the low temperature of 960°C for 10 hours showed dense microstructures and high relative densities. The specimens with 0.0 ≤ x ≤ 0.04 had orthorhombic-tetragonal polymorphic phase boundary (PPB) structure. Tetragonal-pseudocubic PPB structure was observed in specimens with 0.05 ≤ x ≤ 0.07, while the specimen with x = 0.08 has a pseudocubic structure. The structural variation in the specimens is explained by the decreases in the orthorhombic-tetragonal transition temperature and Curie temperature with the addition of Sb⁵⁺ ions. The specimens with 0.05 ≤ x ≤ 0.07, which have tetragonal-pseudocubic PPB structure, had large electric field-induced strains of 0.14%-0.016%. Moreover, these specimens also showed increased d₃₃ values between 280 pC/N and 358 pC/N. In particular, the specimen with x = 0.055 showed particularly enhanced piezoelectric properties: d₃₃ of 358 pC/N, k_p of 0.45, and the electric field-induced strain of 0.16% at 4.5 kV/mm.
