Processing and characterization of lead-free ceramics on the base of sodium–potassium niobate

This is the authors' abstract. We don't add key points for this paper.

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.
