The invention belongs to the technical field of permanent magnet materials, and particularly relates to a ferrite permanent magnet material and a preparation method thereof. The ferrite permanent magnet material comprises a base material and an additive material, and the base material comprises the following components in parts by weight: 80-90 parts of iron oxide, 5-10 parts of strontium oxide, 8-12 parts of nano magnesium oxide and 2-3 parts of barium carbonate; the additive material comprises an additive and a dispersing aid; the additives comprise calcium carbonate, silicon dioxide and bismuth oxide. By optimizing the formula and the preparation method, the obtained ferrite permanent magnet material is crack-free and high in density, the coercive force, the intrinsic coercive force and the residual magnetism of the ferrite permanent magnet material are effectively improved, the overall performance is excellent, and the processing performance is good.
本发明属于永磁材料技术领域，具体涉及一种铁氧体永磁材料及其制备方法。该铁氧体永磁材料包括基础材料和添加材料，所述基础材料按重量份计，包括：氧化铁80‑90份、氧化锶5‑10份、纳米氧化镁8‑12份、碳酸钡2‑3份；所述添加材料包添加剂和分散助剂；添加剂包括碳酸钙、二氧化硅和氧化铋。本发明通过优化配方和制备方法，得到的铁氧体永磁材料无裂纹，密度高，且有效提高了其矫顽力、内禀矫顽力和剩磁，整体性能优异，加工性能好。
