Processing and characterization of lead-free ceramics on the base of sodium–potassium niobate [PDF]
Journal of Advanced Dielectrics, 2018 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
