“…The value of g reported in Table 2 varies between 1.77 and 1.99 which confirms relaxor behaviors. The diffusion factor for all composition fluctuates in the same range (1.7-1.9), however the results show the degree of diffuseness of the phase transition to be highest at the 0.1PMN-0.9BNT composition, which lead to a morphotropic phase boundary (MPB) [22] in this system. In the MPB regions, enhanced dielectric constants are obtained.…”

“…4, NBT–0.6Er ceramics had a coercive field E c of 4.56 kV/mm, which was smaller than 5.26 kV/mm of pure NBT ceramics. Because the addition of Er decreases the high coercive field of NBT, the efficiency for the response of domains to the external field increases 14 . Thus, the lower coercive field facilitates the poling process.…”

“…Thus, the lower coercive field facilitates the poling process. The decreased piezo‐coefficients for a higher amount of Er 2 O 3 doping may result from the decrease of effective dipole moments for the small remnant polarization 14 . The dielectric and piezoelectric properties of different Er‐doped NBT ceramics are summarized in Table I.…”

“…Some modifications on NBT composition have been performed. It has been reported that NBT-based compositions modified with (K 0.5 Bi 0.5 )TiO 3 (KBT) [2,3], NaNbO 3 (NN) [4], and Pb(Mg 1/3 Nb 2/3 )TiO 3 (PMN) [5] showed improved piezoelectric properties and ease of poling as compared with pure NBT ceramics. In the past, the (Na 0.5 Bi 0.5 )TiO 3 -BaTiO 3 compositions (NBT-BT) [3,6] were also developed as the piezoelectric ceramics and their dielectric characteristics were well developed.…”

“…The second is that the excess Bi 2 O 3 addition is used to compensate the vaporization of Bi 2 O 3 during the fabrication process and improve the dielectric characteristics of 0.95 (Na 0.5 Bi 0.5 ) TiO 3 -0.05 BaTiO 3 ceramics. In the past, the (Na 0.5 Bi 0.5 ) TiO 3 -based ceramics were formed by using the solidsolution method and all the raw materials were mixed and calcined in one process [2][3][4][5][6]. However, as we know, different processes to fabricate the ceramics would lead to different results.…”
