  1. The raw materials, the composition, the time of milling, the calcining temperature, the different additives, the sintering temperature and the sintering parameters were investigated. the result showed : it was advantaged to obtain high initial permeability mnzn ferrite with stable frequency characteristic using high - purity raw materials ; in order to obtain mnzn ferrite with high properties, we must control strictly the composition ; it could improve the properties of mnzn ferrite by optimizing calcining temperature. the lower calcining temperature made the permeability higher, and the higher calcining temperature could promote the frequency characteristic of permeability ; we chosen the right time of milling according to the requirement of power diameter ; in order to improve the properties of mnzn ferrite, it is necessary to add effective additives. in this dissertation, the influence of bi2o3 、 moo3 、 k2co3 、 co2o3 were investigated ; the sintering temperature, the time of heat - retaining and sintering parameters were the key factors of preparing high permeability mnzn ferrites

    究結果表明:採用高純度的fe2o3有利於獲得高起始磁導率且頻率特性優良的體;為了制備所需性能的體,需要嚴格控制配方中各種原材料的含量,優配方;由於體活性受預燒條件的影響,所以對不同要求的體選擇的預燒條件就不一樣,適當降低預燒溫度有利於獲得較高的起始磁導率,而為了獲得良好的頻率特性可以適當地提高預燒溫度;根據對體顆粒粒徑的不同需求,可以選擇不同的球時間;而有效的添加劑是改善材料性能的必要條件,本文在添加劑的究中主要對bi2o3 、 moo3 、 k2co3 、 co2o3的影響分別作了詳細地討論;燒結溫度、保溫時間和燒結氣氛是高磁導率mnzn體制備最關鍵的工藝,適宜的燒結工藝可以獲得理想微結構和組成,從而得到高性能的體材料;而從材料的微結構上來看,要提高材料的截止頻率,就要適當地細晶粒、增加晶粒內部的氣孔。
