Such materials have outstanding dielectric properties in ceramics. Such ceramic compositions of (Sr x Ca 1−x ) 3 Ti 2 O 7 (0.2 ≤ x ≥ 0.8) were synthesized using the solid-state technique. The phase, microstructural and microwave dielectric properties of dense sintered (Sr x Ca 1−x ) 3 Ti 2 O 7 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 Sr 2+ doping were observed in the XRD analysis. The Fourier Transform Infrared Spectra (FT-IR) confirmed the bonding characteristics of CaCO 3 , TiO 2 with SrCO 3 . The dielectric constant (ε r ) increased from 6.02 to 42.5 while minimum tangent loss (tan δ) observed was 0.0015.
