Preparation of Nanosized Barium Ferrite Spinel by a Sonochemical Method

摘要：

　　Nanosized barium ferrite spinel particles were prepared with the aid of ultrasound radiation by a precursor approach.A precursor was got by sonicating an aqueous solution of BaCl2,Fe (NO3)3·9H2O and urea firstly.Nanosized BaFe2O4 particles with a size of ca.40nm were prepared after the precursor was heated at 950 ℃ for 15 h.The nanosized barium ferrite particles and the precursor were characterized by powder X-ray diffraction,scanning electron microscopy,FT-IR and differential scanning calorimetry.
