Synthesis and Characterization of Barium Titanate and Cobalt Ferrite Powders for Preparation of Magneto Electric Composites

Abstract

Both Conventional method and auto combustion methods were followed to synthesize powders of Barium titanate and Cobalt ferrite. Nowadays auto combustion synthesis has attracted much more attention due to the inexpensive precursors and ease of batch calculations. Unagglomerated fine powders can be obtained by auto combustion method. During preparation of BaTiO3 and CoFe2O4 by dry route they were calcined at 800o C for two hours and 1000o C for one hour respectively. Powders of Barium Titanate and Cobalt Ferrite synthesized by Auto combustion method were calcined at 1000o C for one hour and 1000o C for two hours respectively. Phases of particular compounds have been confirmed by XRD. For preparing multi ferroic composites the two separate powders are proved to be suitable.
