Multiscale study of ferroelectric–relaxor crossover in BaSnxTi1−xO3 ceramics

Intrinsic pyroelectric properties of thick, coarse grained Ba 1−x Sr x TiO 3 ceramics

“…2(d)). This composition-dependent evolution of microstructure, demonstrating the inhibiting effect of the solute on the grain growth process, is similar to that one reported for other homovalently-or aliovalently-substituted BaTiO 3 -based ceramics [28,29,31,32]. The microstructural features (density, grain size, grain distribution, etc.)…”

Large nonlinear dielectric behavior in BaTi1−xSnxO3

“…The relaxor behavior in these kinds of materials has been in materials with a heterovalent cation substitution as well as in isovalently substituted-solid solutions such as BaTi 1−x Sn x O 3 (BTSn). A systematic investigation of the Sn 4+ -substitution on the phase transition behavior has been reported 9–13 . And tunabale dielectric properties of BTSn were reported by Chen 14 and Lu 15 .…”

Ferroelectric, piezoelectric and electrostrictive properties of Sn4+‐modified Ba0.7Ca0.3TiO3 lead‐free electroceramics

“…3,[7][8][9][10][11] Furthermore, the substitution of Ca 2+ at Ba 2+ in BaTiO 3 -CaTiO 3 system (i.e., to form Ba 1Àx Ca x TiO 3 (BCT) ceramics) results in a slight increase in the Curie temperature (T C ) and on the other hand suppresses the orthorhombic to tetragonal (T O-T ) transition temperature. [13][14][15][16][17] Moreover, the Curie temperature of BT-based electroceramics are sensitive to Sn 4+ content, which obeys the structure-property correlation. 12 Modified BT-based electroceramics, that is, a binary solid solution system composed of ferroelectric BT and nonferroelectric barium stannate (BaSnO 3 ), that is, BaTi 1Àx Sn x O 3 (BTS) has attracted considerable attention due to the presence of diffused type phase transition.…”

“…This is one of the important considerations in developing the temperature stability of piezoelectric properties for various practical applications. [13][14][15][16][17][18][19][20][21][22] In this context, many research groups have reported the dielectric, diffused phase transition, ferroelectric, and piezoelectric properties of BCST ceramics. [13][14][15][16][17] Moreover, the Curie temperature of BT-based electroceramics are sensitive to Sn 4+ content, which obeys the structure-property correlation.…”

[12][13][14][15][16][17][18][19][20][21] However, there is a scarcity of detailed investigation of electrostrictive properties of BT-based lead-free electroceramics, which are correlated with the structure-property-composition having the phase coexistence of orthorhombic-tetragonal (O-T) lattice symmetry, at room temperature. [13][14][15][16][17][18][19][20][21][22] In this context, many research groups have reported the dielectric, diffused phase transition, ferroelectric, and piezoelectric properties of BCST ceramics.…”
