Rare-earth permanent magnets (e.g., Sm-Co, Nd-Fe-B, Sm-Fe-N) are core components of high-performance magnetic materials, widely used in new energy, electronic information, and national defense. Compared with physical methods, chemical preparation techniques for rare-earth permanent magnets exhibit unique advantages such as atomic-level mixing, morphology controllability, and low-temperature synthesis, and are gradually becoming research hotspots. This review systematically summarized the research progress of chemical preparation technologies including the sol-gel method, hydrothermal method, co-precipitation method, thermal decomposition method, and emerging synthetic approaches. It analyzed the microstructure regulation mechanisms and magnetic performance optimization strategies, followed by discussion of current challenges and future development directions in this field.

稀土永磁材料（如Sm-Co，Nd-Fe-B，Sm-Fe-N等）是高性能磁性材料的核心组成部分，广泛应用于新能源、电子信息及国防领域。相较于物理法，化学法在制备稀土永磁材料中具有原子级混合、形貌可调控及低温合成等独特优势，逐渐成为研究热点。本文系统综述了溶胶-凝胶法、水热法、共沉淀法、热分解法以及新兴合成法等化学制备技术的研究进展，分析了其微观结构调控机制与磁性能优化策略，并探讨了当前面临的挑战与未来的发展方向。
