Preparation and characterization of Sr1−xNdxFe12O19 derived from steel-waste product via mechanical alloying

Steel waste product had been used as the main source of raw material in the preparation of permanent magnets ferrites. Steel waste product is an impure material that contains the iron oxide and impurities. The steel waste product is a form of flakes is grinding for several hours to form a fine powde...
