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

Abstract

Polycrystalline strontium barium niobates Sr x Ba1 − 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 (ρD), density of crystallites per unit surface area (Ψ), mechanical properties, and microwave behavior of synthesized materials are reported.
