Method for preparing high-performance permanent magnetic ferrite material from low-purity iron oxide red
The invention relates to the field of permanent magnetic ferrite materials, and discloses a method for preparing a high-performance permanent magnetic ferrite material from low-purity iron oxide red in order to overcome the defects that the preparation cost of an existing high-performance permanent magnetic ferrite is relatively high and the performance of a permanent magnet prepared from the low-purity iron oxide red is relatively low. The permanent magnetic ferrite prepared from the low-purity iron oxide red through the processes of ball milling, pre-pressing, pre-sintering, vibration milling, fine grinding and sintering has the performance similar to or even improved to that of a high-performance permanent magnetic ferrite material prepared from high-purity iron oxide red, and the cost of the low-purity iron oxide red is far lower than that of the high-purity iron oxide red. According to the method for preparing the high-performance permanent magnetic ferrite material from the low-purity iron oxide red, the possibility of preparing the high-performance permanent magnetic ferrite material from the low-purity iron oxide red is realized.
本发明涉及永磁铁氧体材料领域，为了克服现有高性能永磁铁氧体制备成本较高，使用低纯度氧化铁红制备永磁铁性能偏低的不足，公开一种低纯度氧化铁红制备高性能永磁铁氧体材料的方法。低纯度氧化铁红经过球磨‑预压‑预烧‑振磨‑细磨‑烧结的工艺得到的永磁铁氧体，在性能上与高纯度氧化铁红制备的高性能永磁铁氧体材料相近，甚至有所提升，而在成本上，低纯度氧化铁红则要远低于高纯度氧化铁红。本发明的一种低纯度氧化铁红制备高性能永磁铁氧体材料的方法，实现了低纯度氧化铁红制备高性能永磁铁氧体材料的可能。
