<P>PROBLEM TO BE SOLVED: To provide a method for easily and efficiently removing an organic acid, especially an acetic acid component, and to provide hexagonal ferrite powder containing the organic component, i.e. carbon, reduced by the method. <P>SOLUTION: In a method for producing hexagonal ferrite powder by a glass crystallization method, after a glass component and a ferrite component are dissolved and separated by acid treatment using the organic acid, the organic component is separated or decomposed by heating the ferrite component at ≥200°C. <P>COPYRIGHT: (C)2011,JPO&INPIT |
