摘　　要：用天然铁矿作原料 ,不进行磁选 ,直接用固相反应法生产永磁铁氧体。通过对基本配比、预烧温度、烧结温度等条件的探索 ,说明在合适添加剂的条件下 。The permanent magnetic ferrite was prepared by the method of solid phase reaction with the natural magnetite without magnetic separation. The properties dependance on basic proportion, pre reacting temperature and sintering temperature was investigated. The results indicated that high performance magnetic ferrite can be prepared using natural magnetite without any magnetic separation and suitable additives.
