Abstract:

M-type barium ferrite (BaFel2O19) receives much attention due to the remarkable properties of the bulk materials: large magnetic anisotropy, sufficient saturation magnetization, non-toxic, excellent chemical stability and good corrosion resistivity. Using stoichiometric amounts of iron nitrate, barium nitrate and sodium hydroxide as the starting materials, we have prepared BaFel2O19 by hydrothermal synthesis method. The results show that when the n (Fe3+)/n (Ba2+) ratio of 6 and n (OH−)/n (NO3−) ratio of 2, the morphology of BaFe12O19 is hexagonal platelets which approximately 800 nm in length and 50 nm in thickness. The coercivity of BaFe12O19 is 1286 Oe and the saturation magnetization is 23.7 emu/g. The BaFe12O19/phenolic resin composite has been prepared and the permeability of the BaFel2O19/phenolic resin composite was measured.
