ABSTRACT:
A method of producing ferromagnetic metal powder comprises the steps of dipping an iron compound powder in a solution in which an aluminum compound and/or a titanium compound is dissolved, removing solvent from the iron compound powder, reducing the iron compound powder in a reducing atmosphere at an elevated temperature and forming oxide layers on whole surfaces of the individual particles of the iron powder. Ferromagnetic iron powder produced according to this method has both a high coercive force and a high remanence ratio.
