本文研究了碳酸盐—氢氧化物法共同沉淀Ｆｅ２＋、Ｍｎ２＋、Ｚｎ２＋时，反应最终ｐＨ值、沉淀温度、加料方式、加料速度及搅拌强度等因素对恒定共沉粉Ｆｅ２Ｏ３、ＭｎＯ及ＺｎＯｍｏｌ％组成、粒度和颗粒形状的影响，并进一步考查了共沉粉组成与软磁材料性能的关系。在研究基础上确定生产高频低功耗锰锌铁氧体材料Ｈ７２４（ＰＣ４０）和高磁导率锰锌铁氧体材料Ｈ５Ｃ２（μｉ＝１００００±３０％）共沉粉合成的最宜条件。
In this paper, the effects of co-precipitation of Fe2 +, Mn2 + and Zn2 + on the co-precipitation of Fe2O3, MnO and ZnOmol% were studied in the co-precipitation of Fe2 +, Mn2 + and Zn2 + by the reaction of the final pH, precipitation temperature, feeding mode, feeding rate and stirring intensity. , Particle size and particle shape, and further examined the relationship between the composition of co-precipitated powder and the properties of soft magnetic materials. On the basis of the research, the optimal conditions for the synthesis of high-frequency low-power Mn-Zn ferrite material H724 (PC40) and high permeability Mn-Zn ferrite material H5C2 (μi = 10000 ± 30%) were confirmed.
