Effects of chemical modification on the structural and electrical properties of (Ba0.90Ca0.10)0.90(Na0.5Bi0.5)0.10TiO3 ceramics

Abnormal polar nanoregion evolution in (Bi0.09Ba0.91)(Zn0.045Ti0.955)O3 (9BZT‐BT) ceramic

“…The calculated dynamic frequency of PNRs in 9BZT‐BT is in good agreement with attempt frequency f 0 from fitting the experimental data of the permittivity . More details on the relaxor behaviors of ferroelectricity, please consult our previous works .…”

Electrical, magnetic and magnetodielectric properties in ferrite-ferroelectric particulate composites

“…For the ceramics situated at or near the rhombohedral side of the MPB (BNBT6), lower dielectric peaks at T d exhibit strong frequency dependences, implying that ceramics undergo a relaxor phase transition at T d [13]. Among them, (1-x)BNT-xBaTiO 3 -based ceramics have attracted much attention because there exists a rhombohedral-tetragonal morphotropic phase boundary (MPB) near x = 0.06 [24][25][26][27][28][29][30][31][32]; hence, this composition is selected as the starting solution for the development of many ternary lead-free materials.…”

Microstructure, dielectric and ferroelectric properties of (1−x)(0.94Bi0.5Na0.5TiO3–0.06BaTiO3)–xBiFeO3 lead-free ceramics synthesized via a high energy ball milling method

“…These drawbacks can be overcome by forming solid solutions with other components. To improve the properties of BNT, more researches have focused on BNTbased solid solutions such as BNT-(BaSr)TiO 3 [2], BNT-BiFeO 3 [3,4], BNT-Co [5], BNT-Fe 2 O 3 [6], BNT-Bi 0.5 K 0.5 TiO 3 [7,8], BNT-Bi 0.5 K 0.5 TiO 3 -BiFeO 3 [9][10][11], BNT-Bi 0.5 K 0.5 TiO 3 -Sm 2 O 3 [12], BNT-Bi 0.5 K 0.5 TiO 3 -K 0.5 Na 0.5 NbO 3 [13], BNT-BaTiO 3 [14][15][16], BNT-BaTiO 3 -Bi 2 O 3 [17], BNT-BaTiO 3 -K 0.5 Bi 0.5 TiO 3 [18,19], BNT-BaTiO 3 -CaCO 3 [20], BNT-BaTiO 3 -(K 0.5 Na 0.5 )NbO 3 [21][22][23], BNT-BaTiO 3 -Mn [24], BNT-BaTiO 3 -Nb-Co [25], BNT-BaTiO 3 -Nd 2 O 3 [26]. Among them, (1−x)BNT-xBaTiO 3 -based ceramics have attracted much attention because there exists a rhombohedral -tetragonal morphotropic phase boundary (MPB) near x = 0.06 [14][15][16][17][18][19][20][21][22][23][24][25][26].…”
