The invention discloses a low-cost ferrite permanent magnet material and a preparation method thereof, and belongs to the technical field of permanent magnet materials. The invention relates to a low-cost ferrite permanent magnet material, which is prepared from the following raw materials: Fe2O3, SrCO3, La2O3, Co2O3, CaCo3 and a cosolvent. The invention discloses a preparation method of a low-cost ferrite permanent magnet material. The preparation method comprises the following steps: burdening, mixing, dehydrating, carrying out primary forming, crushing, carrying out secondary ball milling, carrying out secondary forming and sintering. In the process of preparing the ferrite permanent magnet material, common iron oxide red is used for replacing Fe2O3, and the low-cost ferrite permanent magnet material is prepared by increasing the replacement amount of combined ions in the material, a proper amount of cosolvent and a specific process. The performance material of the prepared ferrite permanent magnet material is close to that of TDK-FB9, meanwhile, the raw material cost is reduced, and the ferrite permanent magnet material has more advantages in market competition.
本发明公开了一种低成本铁氧体永磁材料及其制备方法，属于永磁材料术领域。一种低成本铁氧体永磁材料，包括以下原料：Fe2O3、SrCO3、La2O3、Co2O3、CaCo3和助溶剂。一种低成本铁氧体永磁材料的制备方法，包括以下步骤：配料、混料、脱水、一次成型、破碎、二次球磨、二次成型和烧结。制备铁氧体永磁材料的过程中，本发明用普通铁红替换Fe2O3，通过增加组合离子在材料中的替换量，适量的助溶剂，以及特有的工艺制得低成本的铁氧体永磁材料。本发明制备的铁氧体永磁材性能料接近TDK‑FB9，同时降低了原料成本，在市场竞争中更具优势。
