摘要：

In this paper, we have investigated the effect of K/Na ratio on the electrical properties of [(K1-x Na (x) )(0.95)Li-0.05](0.985)Ca-0.015(Nb0.95Sb0.05)(0.985)Ti0.015O3 (K1-x Na (x) LCNST) lead-free piezoelectric ceramics prepared by the conventional solid-state method. A pure phase is observed in these ceramics with x = 0.30-0.80, and the K/Na ratio results in the phase transition of K1-x Na (x) LCNST ceramics. The Curie temperature of K1-x Na (x) LCNST ceramics decreases with the increase of Na content. A higher dielectric constant is observed in the ceramic with x = 0.40, and the dielectric loss almost decreases with the increase of Na content. Moreover, an enhanced piezoelectric behavior (d (33) similar to 227 pC/N and k (p)similar to 45.3 %) has been demonstrated in the K1-x Na (x) LCNST ceramic with x = 0.40. Therefore, optimizing the K/Na ratio is an effective way to enhance the piezoelectric properties of K1-x Na (x) LCNST ceramics.
