Preparation method of soft magnetic ferrite auxiliary agent and soft magnetic ferrite
The invention provides a preparation method of a soft magnetic ferrite auxiliary agent and soft magnetic ferrite. The soft magnetic ferrite auxiliary agent is prepared by adding ferrite powder with preset components and a dispersing agent in the preparation process of silicon dioxide aerogel. And the added ferrite powder not only expands the average pore size of the aerogel and enhances the gas and glue discharging capability during sintering of the ferrite, but also can react with the aerogel structure after being fused during high-temperature sintering, and can be used as an auxiliary agent of the ferrite. Therefore, the auxiliary agent for the soft magnetic ferrite has a great effect on finally improving the magnetic performance and the mechanical performance of the ferrite, and can accelerate exhaust and glue discharge and shorten the whole sintering time of the soft magnetic ferrite.
本发明提供一种软磁铁氧体助剂的制备方法及软磁铁氧体。软磁铁氧体助剂是这样制备的，在二氧化硅气凝胶的制备过程中加入预设组分的铁氧体粉体以及分散剂。加入的铁氧体粉体既扩大了气凝胶的平均孔径，增强了在铁氧体烧结时排气排胶能力，又能在高温烧结时发生熔融后与气凝胶结构发生反应，可以作为铁氧体的助剂。因此，本发明软磁铁氧体助剂对于最终提高铁氧体的磁性能和机械性能具有较大的作用，而且可以加快排气排胶，缩短软磁铁氧体的整个烧结时间。
