Abstract

The Phase, microstructural and dielectric properties of Ba_1-x Sr_xTi₄O₉ (0 ≤ x ≤ 0.8) ceramics were investigated. The XRD analysis revealed the formation of orthorhombic structured (Pnmm) BaTi₄O₉ phase. The XRD peaks were observed to shift towards the lower 2θ values with increasing Sr²⁺ contents which may be attributed to the substitution of relatively larger cation of Sr²⁺ (R_Sr = 1.61 Å) for Ba²⁺ (R_Ba = 1.44 Å) in BaTi₄O₉. The dielectric constant (ε_r) increased with Sr²⁺ substitution from 22 to 122 at 1MHz. The maximum value of the dielectric loss was observed 0.11922 for x = 0.8 at 1 MHz.
