Abstract

This study utilized the traditional solid state reaction method to fabricate 0.965(K0.48Na0.52)Nb0.96Sb0.04O3-0.035[(Bi0.5Na0.5)1-xCoxZrO3](KNNS-BNCxZ) lead-free ceramics for the sake of investigating the influences of BiCoZrO3-doped on the crystalline structure, microstructure, and dielectric/piezoelectric properties of the ceramics. The KNNS-BNCxZ ceramics exhibited a perovskite structure, which changed from a three-phase coexistence of rhombohedral-orthorhombic-tetragonal (R-O-T) to orthorhombic (O) with increasing x. The surface morphologies further indicated that different amounts of (BiNa)CoZrO3 played a large effect on the grain growth. In addition, the optimal combined properties (d33 = 418 pC/N, kp = 0.48, Tc = 263 °C) were simultaneously obtained at x = 0.1. Particularly, good thermal stability was observed in a broad temperature range (Ta = 265 °C d33 ≥ 351 pC/N). These results induced that KNNS-BNCxZ ceramics were appropriate candidates for lead-free electronical applications.
