摘　　要：2:17型SmCo永磁体自1977年问世以来,其研究得到很大发展,性能不断提高。因其具有优异的磁性能,已在微波通讯技术、航空航天、国防工业、交通运输业等领域广泛应用。因2:17型SmCo永磁体具有较高的居里温度和较高的磁能积,而成为永磁材料的首选材料。作者介绍了2:17型SmCo永磁的发展过程、磁体的磁性能、制备工艺、应用情况及其发展趋势。2:17 type SmCo permanent magnet obtained great progress since it was invented in 1977, and its properties enhances on and on. Because its excellent magnetic properties, it has abroad applications in many fields such as microwave communication, aviation and traffic transport, et al. Recently, it has been a demand for magnets used in high temperature field which result in a study climax for 2: 17 type SmCo permanent magnet. This article mainly introduces its progressing course, properties, producing technic, application and developing trend.
