摘要
用化学共沉淀法制备锰锌铁氧体微粉,详细研究了加料方式和反应时间对粒度和磁性能的影响。通过分析可以发现,并加的加料方式可以有效地控制成分偏析,结合设备的耐蚀性,采用并加的加料方式的到得锰锌铁氧体微粉粒度较小,磁性能优良。此时,锰锌铁氧体微粉的D50为1.51μm,σs为55.01 A·m2·Kg-1。在控制结晶反应釜内,锰锌铁氧体微粉的粒度达到饱和的时间比磁性能达到饱和的时间短。
In this paper, Mn Zn ferrite powders were prepared by chemical co-precipitation. The effects of feeding ways and reaction time was researched on the distribution of particle size and magnetic properties. The results showed that the concurrent feeding way was helpful to the component segregation. Accounted for the corrosion resistance of the device, the concurrent feeding was the best way. At the same time, D50 was 1.51 μm,σs was 55.01 A·m^2·Kg^-1. In the schematic diagram of agitated reactor, the saturation time of the granularity of Mn-Zn ferrite powders is shorter than that of magnetism.
