Structural and mechanical properties of Sr-doped barium niobate thick films

Polycrystalline strontium barium niobates Sr _x Ba_{1 ? x} Nb₂O₆ (SBN, 0.40 ≤ x ≤ 0.75) were prepared by standard solid state ceramic method at relatively at low temperatures. Thick SBN films prepared by simple, low-cost, screen printing route were characterized by XRD. Preliminary structural analysis exhibits the formation of tetragonal tungsten bronze crystal structure at room temperature. Texture coefficient [TC(hkl)], dislocation density (ρ_D), density of crystallites per unit surface area (Ψ), mechanical properties, and microwave behavior of synthesized materials are reported.
