High remanance of strontium hexaferrite from millscale derived / N. M. Saiden … [et al.]

Strontium hexaferrite was prepared by using millscale as raw materials. Millscale is an impure iron oxide. The mil/scale was milled to obtain < 20um size powder particle in diameter and the oxide powder was separated into magnetic and non-magnetic particle in a I tesla external field. Magneti...
