This paper reports, the structural, dielectric and transport properties of SrxBa1− xNb2O6 [SBN] for x =0.4 and 0.5, prepared by traditional sintering method (solid state reaction technique). The tetragonal tungsten bronze type crystal structure, structural parameters such as the lattice constant (a =12.63946Å, b = 12.63946Å, c =3.978203462Å), average crystallite size (61.62 nm-95.17nm ), and texture coefficient (TC) have been determined using X-ray diffraction data. TGA–DTA analysis reveals that formation of oxide phase takes place beyond 1050Ã?¢Ã?â??Ã?¦C. Rod shaped surface morphology has been obtained. The fundamental vibrational mode observed in finger print region by FTIR reveals formation of SBN ceramics. The variation of real of part dielectric constant (Ã?ŽÃ?Â) and loss tangent (tanδ) was studied at room temperature. The dispersion of dielectric constant with frequency indicates relaxor nature of SBN
