▎ 摘　　要

NOVELTY - Permanent magnet ferrite material with high magnetic properties, comprises raw material A and raw material B, obtained through grinding, molding and sintering. The raw material A comprises 0.1-5 wt.% pretreated graphene oxide, 0.2-1 wt.% calcium metaborate, 0.5-3 wt.% vitamin C, 20-30 wt.% alcohol, 0.1-0.5 wt.% oxalic acid, 60.5-79.1 wt.% tricobalt tetroxide. The raw material A prepared by mixing the above raw materials. The raw material B is a calcined material whose molecular formula is (I), and prepared by (i) taking strontium carbonate (SrCO3), calcium carbonate (CaCO3), lanthanum oxide (La2O3), iron oxide (Fe2O3), cobalt oxide (Co3O4) and zinc oxide (ZnO), (ii) wet grinding the mixed material for 1-5 hours to obtain grinding material, and (iii) drying the grinding material until the moisture content is less than 3%, crushing through an 80-mesh sieve, pre-calcining at 1220-1280°C for 60-150 minutes and crushing. USE - Permanent magnet ferrite material with high magnetic properties. ADVANTAGE - The permanent magnetic ferrite material has easy orientation, increased compactness, increased density, enhanced magnet toughness, reduced forming cracks, improved yield, and the obtained permanent magnet ferrite has excellent performance.
