Influence of Different Precursors upon Characterization of Bismuth Titanate Powders Prepared by Chemical Methods
Bismuth titanate Bi4Ti3O12 powders had been successfully prepared from different starting materials by chemical methods and characterized by XRD, SEM and DTA. Our efforts in this paper were directed to disclose the influence of precursors on the particle characterization. It was shown that different precursors affected the crystalline temperature, particle nucleation and growth rate greatly, leading to different particle size and morphology. Excess addition of Bi2O3 was found to be dominant in lowing crystalline temperature while spherical particles was probably attributed to large growth rate and use of glacial acetic acid as a solvent medium.
