Published in 2017 at "Journal of Materials Science: Materials in Electronics"

DOI: 10.1007/s10854-017-7715-7

Abstract: LaAlO3 as an effective additive for modification of KNN system has never been systemically discussed before. Here, (0.96−x)K0.48Na0.52NbO3–0.04Bi0.5Na0.5ZrO3–xLaAlO3 (KNN–BNZ–xLA) ceramics have been synthesized by traditional solid-state sintering with a special emphasis on the influences of… read more here.
