Melting the production manner of the hexagonal ferrite magnetic powder and the raw materials blend which includes

摘要

An aspect of the present invention relates to a method of manufacturing a hexagonal ferrite magnetic powder comprising preparing a melt by melting a starting material mixture comprising a hexagonal ferrite-forming component and a glass-forming component; rapidly cooling the melt to obtain an amorphous material comprising 0.3 to 2.0 weight percent of carbon atoms; heating the amorphous material to a temperature range of 580 to 700°C and maintaining the amorphous material within the temperature range to precipitate hexagonal ferrite magnetic particles; and collecting the hexagonal ferrite magnetic particles precipitated.
