Abstract

Highly stable, organic-based barium titanate (BaTiO3) sols were developed by the low cost and straightforward “organosol”-precipitation and auto-combustion process of amorphous organic precursors. BaTiO3/CoFe2O4 nanocomposites with core/shell structures embedded in a BaTiO3 matrix were also obtained using this process. The particles are systematically characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric and differential thermal analyses (TGA/DTA), infrared spectroscopy (IR) and by laser granulometry for particle size distribution determination.
