Ferroelectric properties of strontium bismuth titanate(SrBi4Ti4O15) synthesized using solution combustion technique

The ferroelectric properties of layer-structured Strontium Bismuth Titanate (SBT) have been investigated in this study. SBT was prepared using solution combustion technique with glycine as a fuel. Single-phase formation of the layer-structured compound of SBT with orthorhombic structure was achieved after calcinations at 800 degrees C, and was confirmed by x-ray diffraction studies. Scanning electron micrograph shows that the grains exhibit a plate like morphology and possesses fine particle size. The as prepared sample exhibits ferroelectric properties with remnant polarization of 2Pr = 1.84 mu C/cm(2) at coercive field 2Ec = 2.61 kV/cm and displays low dielectric loss. Its ferroelectric transition temperature (T-c) is found to be 450 degrees C.
