Process Control Using Ft-Ir Analysis of Batio3 From Ultrasonically Activated Baco3 And Tio2
Barium Titanate (BaTiO3) was prepared from reagents materials BaCO3 and TiO2 by modified solid-state reactions. The reagents were activated ultrasonically using an ultrasonic processor for 5 minutes and 30 minutes in water and acetone mediums. Activation effects on the lattice dynamics of the calcined BaTiO3 powders have investigated using Fourier transform infrared spectroscopy (FT-IR) analysis in this study. The results of FT-IR confirmed that all powders were pure BaTiO3 ceramics. There were no extra peaks of sample ultrasonicated in the acetone medium. But, the results pointed out that there were some barium carbonate (BaCO3) impurities and water in barium titanate (BaTiO3) powders activated in water.
