摘　　要：究了用磁铁精矿制取超纯铁精矿，并用超纯铁精矿取代铁红或铁鳞生产锶铁氧体预烧料。在ｎ＝５．６和预烧温度为１２８０℃，预烧时间为１ｈ的条件下。In this paper,ferric oxide powders or roll scales were replaced by superpure magnetite concentrate proprated with magnetite concentrate to produce the pre sintering product of strontium ferrite.The experiments showed that the pre sintering product of strontium ferrite with high quality could be obtained under the conditons of n=5.6,the presintering temperature of 1280℃ and the persintering time of 1h.
