Effects of Alkali Metal Content and Sintering Temperature on the Structure and Electrical Properties of (Na_0.52K_0.48) _0.94+xLi_0.06-xNb_0.94Sb_0.06O₃Lead-Free Piezoelectric Ceramics

Abstract:

Alkali niobate lead-free piezoelectric ceramics with nominal compositions [(Na_0.52K_0.48)_{0.94+ x}Li_0.06-x](Nb_0.94Sb_0.06)O₃((NK)_xLNS) were prepared by normal sintering. Crystalline phase, piezoelectric properties and sintering behavior of (NK)_xLNS ceramics were investigated with a special emphasis on the influence of alkli metal content. The x-ray diffraction patterns and the corresponding calculation of lattice parameters indicated that a phase transition from tetragonal to orthorhombic symmetry occurs as x=0.01, resulting in enhanced piezoelectric constant and planar electromechanical coupling coefficient of 266 pC/N and 38.5%, respectively. With x=0.01, the ceramics sintered at 1050 C show higher density and better electrical properties. Our results indicate the importance of sintering temperature and elaborate compositional control for enhancing piezoelectric properties in niobate-based ceramics.
