Synthesis and Characterization of Ferroelectric Bismuth Titanate (Bi4Ti3O12)

The Lead free, Bi4Ti3O12 has been synthesized by sol-gel method. The synthesized samples have been subjected to the structural, morphological, P-E hysteresis loop measurements. The X-Ray diffraction (XRD) studies have confirmed the pure phase Bismuth Titanate Bi4Ti3O12 with orthorhombic symmetry. The Scanning electron microscope (SEM) studies have shown the good surface morphology. The hysteresis measurement of BIT is also done to confirm the ferroelectric property of the material. The values of remnant polarization (P-r) and coercive field (E-c) is found to be dependent on applied electric field.
