▎ 摘 要
NOVELTY - Graphene rare earth permanent magnetic material comprises 20.6-23.4 wt.% neodymium, 6.6-7.5 wt.% praseodymium, 0.95-1.20 wt.% boron, 0.4-0.6 wt.% cobalt, 0.11-0.15 wt.% copper, 2-2.4 wt.% lanthanum, 1.7-2.1 wt.% cerium, 1-5 wt.% graphene, and iron (remaining amount). USE - Used as the graphene rare earth permanent magnetic material. ADVANTAGE - The permanent magnetic material: has good temperature resistance, conductivity and magnetic performance, excellent performance, and has stable performance; does not contain heavy rare earth elements, e.g. terbium and dysprosium heavy rare earth elements; and is economical, and is good for great utilization of rare earth resource, which improves product yield. The method: is simple, and easy to control; and has low production cost, and has high production efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene rare earth permanent magnetic material.
