Structure and dielectric studies of nano-composite Fe2O3: BaTiO3 prepared by sol–gel method

Structure and dielectric behavior of nano-structure ferroelectric BaxSr1−xTiO3 prepared by sol–gel method

“…This is might be due to that the strontium titanate is usually employed to lower the Curie point [22]. However, the rate of increase in inverse permittivity for BT is sharper than that obtained for B50ST.…”

“…. [1][2][3][4][5][6][7][8][9][10][11][12]. The most remarkable property of BT and BST is related to its high dielectric constant, where the room temperature dielectric constant of BaTiO 3 ceramics is known to be greater than 2000 [13].…”

Synergetic improvement in electromagnetic interference shielding characteristics of polyaniline-coated graphite oxide/γ-Fe2O3/BaTiO3 nanocomposites

“…Therefore, BaTiO 3 was introduced as the additive to improve the electrical property of nanocomposite and to overcome the insufficient electric conductivity of GO. BaTiO 3 and g-Fe 2 O 3 have been widely applied in EMI shielding due to their high dielectric and coercive force properties [25][26][27]. The ferroelectrics of BaTiO 3 exhibit various electrical and magnetic properties of which the complex permeability and permittivity are important in determining their high frequency characteristics.…”

Determination of A.C. Conductivity of Nano-Composite Perovskite Ba<sub>(1- x - y)</sub>Sr<sub>(x)</sub>TiFe<sub>(y)</sub>O<sub>3</sub> Prepared by the Sol-Gel Technique

“…Barium titanate, which is the host material for doping with the Sr has been extensively employed in several industrial applications, including dynamic random access memory (DRAM) capacitors, microwave filters, infrared detectors and dielectric phase shifters, due to its excellent ferroelectric, dielectric, piezoelectric and pyroelectric properties [1][2][3][4][5]. It was previously reported that for the ABO 3 perovskite, different A-site and B-site dopants (where A = Ca, Sr, La; B = Nb, Ta, Zr) were used to modify the electrical properties of BaTiO 3 based compositions [6][7][8][9].…”

“…either in powder or thin film forms. It was suggested previously that in Fe-doped (Ba 1-x Sr x )TiO 3 micro-structural and dielectric properties were modified by controlling the Fe concentration (0.01 ≤ x ≤ 0.20 mol%) with fixed Sr concentrations [1][2][3][4][5][6][7][8]. Barium strontium titanate (BST) with high dielectric constant (ε) attracted much interest as materials for environmentally applications (dielectric for capacitors, actuators, etc.).…”
