Abstract: Abstract This study investigated the effect of LiNbO3 modification on the dielectric, ferroelectric and electromechanical strain properties of Bi1/2Na1/2TiO3–SrTiO3 (BNT–ST) lead–free relaxor ceramics. The sintering temperature for lead–free BNT–ST relaxor ceramics was slightly decreased from… read more here.

Abstract: In this study, the stabilization of ergodicity and electromechanical strain properties of lead‐free ternary 0.75Na1/2Bi1/2TiO3–0.24SrTiO3–0.01ABO3 piezoceramics (BNT–24ST, ABO3 = BaZrO3 (BZ), CaTiO3 (CT), and BiFeO3 (BF)) were investigated. The relaxor state could be stabilized in BZ‐and BF‐modified… read more here.
