  • Effect of High Energy Ball Milling on the Magnetic

    Jul 03, 2019 High-density fine-grained Ni0.5Zn0.5Fe2O4 ferrite ceramics were synthesized by spark plasma sintering (SPS) in conjunction with high energy ball milling. The precursor powders were milled for 20 h, 40 h, and 60 h, respectively, and the milled powders were all sintered for 5 min at 900 C. All the samples exhibit a single spinel phase. With increasing of the ball milling time, the relative ...
