Abstract

Permanent ferrite magnet materials are extensively employed due to their exceptional magnetic properties and cost-effectiveness. The fast development in electromobile and household appliance industries contributes to a new progress in permanent ferrite materials. This paper reviews the deveolpement and progress of permanent ferrite magnet industry in recent years. The emergence of new raw material, the advancement of perparation methods and manufacturing techniques, and the potential applications of permanent ferrite materials are introduced and discussed. Specifically, nanocrystallization plays a crucial role in achieving high performance at a low cost and reducing reliance on rare earth resources, and therefore it could be a promising development trendency.

摘要

永磁铁氧体材料凭借其优异的磁性能和高性价比而应用广泛。随着电动汽车和智能家电领域的 快速发展,永磁铁氧体材料在制备工艺及理论研究方面也迎来了新的发展机遇。本文围绕原料的更新 换代、技术革新及涉及的应用领域等方面进行介绍和评述。原料方面,高纯铁精矿因其储量大、加工 成本低及成分稳定等特点而备受关注。技术革新方面,离子取代和组合添加剂的使用能有效提升永磁 铁氧体磁性能。放电等离子烧结及微波烧结等新型烧结方式兼具高效和低能耗的特点,但由于其生产 成本高、设备难以大型化,推行工业化仍需进一步研究。永磁铁氧体材料具有好的耐腐蚀性、温度稳 定性等优势,除了在电机领域得到了广泛应用,**些年在微波材料和水处理领域也得初步应用。尤其 是纳米化技术,可通过阻止多畴结构的形成来实现得到铁氧体材料的高性能,极大程度降低材料对稀 土资源的依赖,被认为是未来的方展方向之一
