摘要
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(1-x)(K_(0.5)Na_(0.5))NbO_(3)-xBaTiO_(3) system and in compositions with x=0.05 and 0.06 additionally doped by Ni^(3+) cations have been studied.
