▎ 摘  要

NOVELTY - A magnetic material comprises 50-60 parts mass, preferably 55 parts mass ferric oxide, 10-15 parts mass, preferably 13 parts mass lanthanum oxide, 10-15 parts mass, preferably 12 parts mass carbonyl iron powder, 5-8 parts mass, preferably 8 parts mass graphene oxide, 3-6 parts mass, preferably 5 parts mass neodymium oxide, 3-5 parts mass, preferably 3 parts mass boron oxide, 1-5 parts mass, preferably 2 parts mass barium carbonate and 0.5-1 part mass, preferably 1 part mass strontium carbonate. USE - Magnetic material for motor. ADVANTAGE - The magnetic material has excellent performance, synergistic effect due to the addition of carbonyl iron powder and graphene oxide, magnetic properties, has coercivity of 410-415 kA/m, remanence of 480-493 mT, and a maximum magnetic energy of 52-55 kJ/m3. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the magnetic material.
