Abstract
PURPOSE: To provide a method for producing a ferromagnetic iron oxide powder, comprising causing β-FeOOH produced by the hydrolysis of ferric chloride to adhere to a ferromagnetic iron oxide powder, thereby to obtain a ferromagnetic iron oxide powder having a homogeneous and smooth configuration and well adapted as a recording element of a magnetic recorder.
