Research Progress and Challenges in Chemical Preparation of Rare-earth Permanent Magnets
摘要
Abstract
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.关键词
