摘　　要：本文用天然铁矿石直接法制备W－型铁氧体，借助于XRD、TEM、VSM等技术对合成的铁氧体的结构、形貌和磁学性能进行了表征。结果表明，用天然铁矿石可以制备出高性能的W－型铁氧体SrZn_2Fe_(16)O_(27)磁性材料。其磁学性能分别为：σ_s＝92.59emu／g，σ_r＝54.93emu／g，Hc＝2.6kOe。In this paper, the W - type ferrite was prepared by using natural ferrous - mineral with direct method. By means of XRD, TEM, VSW et al. techniques, the structure, alphaform, magnetic properties of the ferrite was synthesized. The result shown that natural ferrous - mineral could used to prepare the high performance W - type ferrite materials. The magrietic performances as follows: σs = 92.59emu/g, σr, =54. 93emu/g, Hc = 2. 6kOe.
