Abstract:In the present work, nano Mn and MnZn ferrite powders were prepared by detonation of emulsion explosives, XRD(X-ray diffraction),TEM(transmission electron microscope) and VSM(vibrating sample magnetometer) experiments were carried out respectively to characterize and research the prepared powders. Results indicated that the average particle size of the raw Mn and MnZn ferrite powders was around 30nm, and Zn2+ seriously destroyed and reduced the dispersity and homogeneity of the powders although they were successfully doped in nano-Mn ferrite crystals. The average particle size, the specific residual magnetization(sigma(r)) and the coercivity(Hc) of the powders were all decreased with the increasing of the hexogen(for short, RDX) content.
