Abstract

Polycrystalline Sr1-2xNaxSmxBi4Ti4O15 (SNSBT) belongs to bismuth layer structured ferroelectric (BLSF) materials with x=0.1 have been prepared by sol gel method. XRD analysis confirms single phase formation with orthorhombic structure. Scanning electron micro graph of the material shows plate like grains with random orientation. Dielectric and impedance measurements carried out from room temperature to 600oC at different frequencies. Piezoelectric and electromechanical coupling coefficients are calculated from resonance and anti-resonance frequencies. Cole-Cole plots showed non-Debye behaviour.
