Preparation of barium ferrite nano particles in ethanol/water media and study of its physical properties

Barium ferrite nano particles was prepared by co-precipitation route using (ethanol/water) solutions of iron chloride FeCl3.6H2O and barium chloride BaCl2.2H2O with a Fe/Ba molar ratio of 15. the produced powder was dried at 80 ºC for 12 h and then calcined at various temperatures for 2 h. Nano particles of barium ferrite with particle size of about 30 and 70 nm were observed from SEM micrographs of the samples synthesized and calcined at 800˚C and 1000 ºC for 2 h, respectively.
