Investigation of the effect of Sr-substitution on the structural, morphological, dielectric, and energy storage properties of BaTiO3-based perovskite ceramics

Optimization of switching charge and recoverable energy density mediated by structural transformation in Sr-substituted BaNiO3 perovskites

“…24 Perovskite oxides have the general formula ABO 3 , where mono, di, or tri-valent cations of alkali or alkaline earth metals occupy the A-sites whereas tetra, penta or hexavalent cations of transition metals occupy the B-sites. 25,26 A perfect crystalline unit cell of perovskite has cubic symmetry with a pm 3m space group where each B-site cation is coordinated by six oxygen anions in a BO 3 octahedron framework, and each A-site cation reclined in the 12-fold coordinated site in between the octahedra. 27,28 The reason behind the ferroelectricity in these oxides is the creation of an electric dipole because of the displacement of the B-site cation from the centre of symmetry in the 001, 110 or 111 directions, leading towards the tetragonal, orthorhombic, or rhombohedral structures, respectively, under the Curie temperature.…”

“…30 Several ferroelectric perovskites such as BaSnO 3 , (Na,Bi)TiO 3 , Ba(Zr,Ti)O 3 and (Ba,Sr)TiO 3 have been reported to have good energy storage characteristics. 1,18,22,25 Recently, many researchers have been studying the energy storage capabilities of the ferroelectric perovskites. For example, Zhang et al investigated the improved energy density and higher efficiency in Bi 0.5 Na 0.5 TiO 3 (BNT) under a low electric eld.…”

Effect of Strontium Substitution on the Tribocatalytic Performance of Barium Titanate

“…BaTiO 3 , the most widely studied ABO 3 type perovskite ferroelectric material, has ferroelectric properties, and its internal electric field induced by spontaneous polarization can promote carrier separation [13][14][15]. In addition, the perovskite lattice of BaTiO 3 can accommodate ions of different sizes while maintaining the good perovskite structure, allowing some doping elements to be localized in BaTiO 3 [16,17]. In the tribocatalytic field, Yang et al [18] reported that Ba 0.7 Sr 0.3 TiO 3 showed tribocatalytic performance via substitution.…”

Ca doping to enhance energy storage performance of lead‐free SrTi0.99Mn0.01O3 thin films with low hysteresis

“…[ 1–5 ] Energy storage density ( W ), energy storage efficiency ( η ) and thermal stability are usually utilized for evaluating dielectric capacitors. [ 6–11 ] Generally, in order to achieve excellent energy storage performance, the difference between maximum polarization [ 12,13 ] ( P max ) and remanent polarization [ 14 ] ( P r ), breakdown strength [ 15 ] ( BDS ) and dielectric constant ( ε ) are used as optimization targets. [ 16–20 ] There is another factor that is often ignored.…”
