Resumen o descripción

Powder mixture of magnetite (Fe3O4) and elemental zinc (Zn) was high energy ball milled looking forward to synthesize a composite material able to enhance magnetic coercivity (Hc). Results revealed up to 449.1 Oe for powder mixture treated for 540 min milling. Specific saturation magnetization (σs) of 50.35 and 43.7 emu/g was respectively reached in samples ball milled for 300 and 540 min. Moreover, specific remanent magnetization (σr) of 3.976 and 9.507 emu/g was respectively obtained for samples ball milled for 60 and 540 min. It is speculated that the degree of magnetization developed on studied samples might be influenced from the metallic-contamination derived from milling wear media such as Fe, Cr and Ni (stainless steel). The Zn–ferrite powder mixture processing and its preliminary magnetization results are discussed.
