Dielectric and Ferroelectric Properties of LiNbO3 Doped Lead-free Bi0.5Na0.5TiO3 (BNT) Ceramics

Synthesis and characterizations of (1-Φ) (NBT-BT)-ΦSB ex T ceramics for NVRAM applications

“…For minimizing the coercive field (E c ), NBT system is modified by various means like: doping, substitution or by preparing solid solutions [6], which are studied in bulk, single crystal and thin film forms [7][8][9][10]. Out of these different modified NBT materials, (1-x)Na 0.5 Bi 0.5 TiO 3 -xBaTiO 3 /NBT-BT system near morphotropic phase boundary (MPB) region shows promising dielectric, piezoelectric and ferroelectric properties.…”

“…Nevertheless, by doping lithium niobate (LiNbO 3 ) with super high T c at about 1,210°C (Jaffe, Cook, and Jaffe 1971), the T c of BNT-BT ceramics will be increased correspondingly. Furthermore, LiNbO 3 as one of the ABO 3 -type ferroelectrics has been widely used to modify the BNTbased materials (Kim et al 2011;Kim et al 2012;Hao et al 2013). Jin et al (Kim et al 2011) reported that the BNT-LN ceramics at the BNT-rich have rhombohedral-tetragonal MPB in the range of 0.03-0.05 mol LN.…”

This work suggests that the MPB will be existed in BNT-BT-LN ceramics at the BNT rich.…”
