Effect of processing route on the phase formation and properties of Bi4Ti3O12 ceramics
Source abstract
Abstract
Abstract Our efforts were directed to the preparation of bismuth titanate—Bi 4 Ti 3 O 12 (BIT) by two procedures: mechanically assisted synthesis and polymeric precursor method to display a variety of their advantages. To follow the nucleation and phase formation of BIT, XRD and Rietveld refinement analysis were used and it was shown that Bi 4 Ti 3 O 12 ceramic can been successfully prepared from nano-sized powders obtained by both methods. The ferroelectric properties were determined and the loops from BIT obtained by polymeric precursor method were not fully saturated with a remnant polarization of 20 μC/cm 2 and coercitive field of 1500 kV/cm. BIT obtained from powders prepared by mechanically assisted synthesis shows a remnant polarization of 0.65 μC/cm 2 and coercitive field of 1050 kV/cm. The grain morphology may be the factor causing the observed differences.
