Method of manufacturing hexagonal ferrite powder, hexagonal ferrite powder, magnetic recording medium and method of manufacturing magnetic recording medium
The method of manufacturing hexagonal ferrite powder includes preparing a hexagonal ferrite precursor by mixing an iron salt and a divalent metal salt in a water-based solution, and converting the hexagonal ferrite precursor into hexagonal ferrite within a reaction flow passage, within which a fluid flowing therein is subjected to heating and pressurizing, by continuously feeding a water-based solution containing the hexagonal ferrite precursor and gelatin to the reaction flow passage.
