铈基永磁材料因其优异的性价比和独特的相结构而受到学术界和工业界的广泛关注。特征在于，Ce基烧结磁体具有随着Ce含量变化而广泛可调的磁性能。因此，它们可以用来满足许多不同的应用需求，从包装市场的驱动电机等的内禀磁性能，相组成，和显微组织的Ce基烧结磁体与不同的Ce含量进行了总结。介绍了商用铈基烧结磁体的温度稳定性、耐腐蚀性、力学性能和热膨胀性等使用性能。指出了今后铈基磁体的研究和发展趋势。
Ce-based magnets have attracted extensive attention in both academia and industry due to their excellent property–price ratio and distinctive phase structures. Characteristically, Ce-based sintered magnets have widely tunable magnetic properties with changing Ce contents. Therefore, they can be used to meet many different application requirements from packaging market to driving motors, etc. The intrinsic magnetic properties, phase composition, and microstructures of the Ce-based sintered magnets with different Ce contents have been summarized. The service performances such as temperature stability, corrosion resistance, mechanical properties and thermal expansion of commercial Ce-based sintered magnets are introduced. The research and development trends of the Ce-based magnets in the future are pointed out.
