“…The lattice strain (η) was calculated through the equation , In Table , the deviation in the calculated lattice strain and crystallite sizes of all prepared Ba 1– x Sr x Ti 4 O 9 , (0.00 ≤ x ≤ 0.06) ceramics samples with compositions is shown. When the concentration of the dopant element is increased, the microstrain decreases due to the size of the dopant element being greater than the host ions, as shown in Table .…”

The structural, microstructural, and microwave dielectric properties of Ba1–x Sr x Ti4O9, (0.0 ≤ x ≤ 0.06) ceramics samples synthesized by a conventional route were investigated. These structural, microstructural, and dielectric properties were recorded using X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared (FTIR) and impedance analyzer spectroscopies. Ti–O octahedral distortion was observed due to Sr2+ addition. The microwave dielectric properties were interrelated with various Sr2+ concentrations. Excellent microwave dielectric properties, i.e., high relative permittivity (ϵr = 71.50) and low dielectric loss (tan δ = 0.0006), were obtained.

Cerium (Ce)-doped Ni0.5Cd0.5CexFe2−xO4 (0.0 ≤ x ≤ 0.20) was synthesized using the sol–gel auto-combustion method. X-ray diffraction (XRD) analysis revealed that all the samples retained spinel cubic crystal structure with space group Fd3m at 800 °C. Crystal structure parameters, such as lattice constant, average crystallite size, and X-ray density were estimated from the major XRD (311) peak. Bulk density and porosity were also calculated. The average crystallite size was estimated to be in the range of 20–24 nm. SEM images displayed agglomerated particles with a porous morphology. The dielectric constant (ε′) increased and the dielectric loss tangent (tanδ) decreased with rising Ce concentration. The hysteresis loop (M–H loop) was measured at room temperature using a vibrating-sample magnetometer (VSM), which showed a nonlinear decrease in magnetization and coercivity with increasing Ce concentration.

Two-dimensional (2D) perovskite-like slabs are a class of materials that are structurally identical but have one direction of reduced dimensionality, giving the material a layered or sheet-like structure. Such materials have outstanding dielectric properties in ceramics. Such ceramic compositions of (SrxCa1−x)3Ti2O7 (0.2 ≤ x ≥ 0.8) were synthesized using the solid-state technique. The phase, microstructural and microwave dielectric properties of dense sintered (SrxCa1−x)3Ti2O7 ceramics (0.2 ≤ x ≥ 0.8) were analyzed by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier transformed infrared spectroscopy (FT-IR) and impedance analysis. All the samples have a Tetragonal phase structure with a space group of I4/mmm formation and the crystalline size, dislocation density and lattice strain changes with respect to Sr2+ doping were observed in the XRD analysis. The Fourier Transform Infrared Spectra (FT-IR) confirmed the bonding characteristics of CaCO3, TiO2 with SrCO3. The dielectric constant (εr) increased from 6.02 to 42.5 while minimum tangent loss (tan δ) observed was 0.0015.
