摘      要：Rare earth resources in China are the most abundant, the production capability ranks second in the world. The first generation of rare earth-transition group permanent magnet alloy RECo5 developed in 1970 s started using rare earths as substantial components. Because of the need of product diversity and to utilize rich resources of mixed rare earth metals, researchers are working on substitution of expensive elemental rare earth metals with cheaper cerium or mixed rare earths (rich in cerium, lanthanum or neodymium) to make lower cost permanent - magnet such as CeCo5. Ce[CoCuFe]5. etc.
