METHOD FOR MANUFACTURING POWDER FOR ELECTROMAGNETIC WAVE ABSORBER

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing flat powder used for an electromagnetic wave absorber, or the like. SOLUTION: In the method for manufacturing the flat powder for the electromagnetic wave absorber, oxygen content in an atmosphere in the case of flattening the powder is controlled to 5-20% to prevent readhesion during treatment and perform flattening in high efficiency.
