Solid solutions of Ba(1 − x)CaxTiO3 (0 
x 1) ceramics were synthesized by the mixed oxides solid-state route for solid Perovskites ceramics material. The phase, structural, microstructural and microwave dielectric properties of the synthesized material were thoroughly investigated. The X-ray diffraction analysis confirmed the formation of orthorhombic structure with no secondary phases. The values of dielectric constant and Q × f were enhanced with Ca+2 substitutions for Ba+2 in Ba(1 − x)CaxTiO3. The values of the dielectric constant vary from 39 to 190 and Q × f reached to a maximum value of 5747 GHz. The maximum value of the dielectric loss (tan δ) observed was 0.00052. Ba(1 − x)CaxTiO3 can be a promising composition for microwave dielectric applications.
