磁性材料的基本概念
1.磁性材料定义
磁性材料是功能材料的一种,主要指利用材料的磁性能和磁效应来实现对能量和信息的转换、传递、调制、存储和检测等功能作用的材料。
2.磁性材料分类及其主要应用领域
磁性材料按照磁性能特征主要分为软磁、硬磁、半硬磁三类。由于磁性材料主要用于能量和信息的传递、转换领域,所以在电子信息产业和节能环保产业快速发展的今天具有广阔的用武之地。
(1)软磁材料
指较容易磁化和去磁的材料, 磁感应强度较高。普遍运用于通讯、广播、电视、仪表等需要对外磁场变化有高灵敏性反应的领域。它是发展较早、品种全、产量多、应用广泛的磁性材料。在软磁材料中,铁氧体软磁是目前使用广泛、品种多、的类型。铁氧体软磁是信息材料支柱产业之一,电子信息产业、新型照明技术、电子产品数字化等飞速发展地推动了对软磁铁氧体材料的需求。
(2)硬磁材料
又称为永磁体,这是因为它经磁化后仍能保持较强的磁性。大量应用于电动机、发电机、扬声器、轴承、紧固件和传动装置等需要一个有恒定磁场的领域。永磁材料的主体是稀土永磁和铁氧体永磁。稀土永磁材料应用广泛、需求量大、前景乐观,如核磁共振、计算机及设备、移动通讯设备、风力发电及电梯等都需要大量的稀土永磁材料,电动汽车、混合动力汽车、永磁变频空调更是国内稀土永磁市场的新增长点。铁氧体永磁材料主要占据传统中低端产品领域, 如扬声器、吸附磁体、玩具电机、磁选器件。
(3)半硬磁材料
性能介于软磁材料和硬磁材料之间,特点是在小于一定的外部干扰磁场下具有稳定的剩余磁感应强度(类似硬磁性材料),但在大于一定的磁场条件下易于改变磁化方向(类似软磁材料)。半硬磁材料是一种用作动态使用的材料, 在当今趋于智能化的社会,动态使用情况日益增多,大量用于硬盘、磁带、信用卡等信息存储设备以及继电器、半固定存储器和警报器等设备中,有很好的发展前景。
