Perovskite Lattice

Lead-free sodium–potassium niobate-based piezoelectric materials are most intensively studied in order to replace the widely used Pb-based ones. In this work, the effects of modification of compositions by donor and acceptor dopants in the A- and B-sites of perovskite lattice on structure, dielectric, ferroelectric, and piezoelectric properties of ceramics from Morphotropic Phase Boundary in the ([Formula: see text])(K[Formula: see text]Na[Formula: see text])NbO3–[Formula: see text]BaTiO3 system and in compositions with [Formula: see text] and 0.06 additionally doped by Ni[Formula: see text] cations have been studied.

Sintering Method

Lead-free alkaline niobate-based piezoceramics, (Na0.52K0.435Li0.045)Nb0.87Sb0.08Ta0.05O3 (abbreviated KNLNT-S8), were prepared by conventional solid-state sintering method. The effects of sintering temperature on microstructure and piezoelectric properties of the (Li, Sb, Ta)-modified (Na, K) NbO3 were investigated. Microstructure of the samples sintered at different temperatures was observed by scanning electron microscopy (SEM) and optical microscopy. The KNLNT-S8 sample sintered at 1100°C possessed highest piezoelectric constant and high-field piezoelectric strain coefficient of 332 pC/N and 530 pm/V, respectively, with electromechanical coupling factors of 0.52 and of 0.48.
