NEODYMIUM-BASED RARE-EARTH PERMANENT MAGNET AND PROCESS FOR PRODUCING SAME

摘要

Provided is a neodymium-based rare earth permanent magnet having a purity of 99.9 wt% or higher excluding gas components and component elements. The present invention can remarkably improve the magnetic properties in a neodymium-based rare earth permanent magnet by highly purifying the magnetic materials. Furthermore, the present invention aims to provide a high-performance neodymium-based rare earth permanent magnet with improved heat resistance and corrosion resistance, which are inherent drawbacks of magnetic materials.
