Structural and Mechanical Properties of Sr-Doped Barium Niobate Thick Films

Polycrystalline strontium barium niobates SrxBa1-xNb2O6 (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 for-mation of tetragonal tungsten bronze crystal structure at room temperature. Texture coefficient [TC(hkl)], dislocation density (rho D), density of crystallites per unit surface area (psi), mechanical properties, and micro-wave behavior of synthesized materials are reported.
