Structure and magnetic properties of ballmill prepared In this study, nanocrystalline Ni 0.64 Zn 0.36 Fe 2 O 4 powders were prepared by high energy ball milling of ZnO, NiO and Fe 2 O 3 powder mixtures. The synthesized powders were heat treated at different temperatures varying from 400 °C to 750 °C.Structural properties of the asmilled and the postheat treated powders were studied by means of Xray diffraction (XRD) technique, scanningStructure and properties of barium ferrite powders The milling process of examined Fe2O3 and BaCO3 mixture leads to increase the content of Fe 2O3 phase and decrease the content of BaCO 3 (Fig.7,8). After 30 hours of highenergy ball milling the content of Fe2O3is 91 wt.% and 9 wt.% for BaCO3 phase. Milling process causes enriching of surface layer of powder particles by Fe2O3.
Preparation and microwave absorbing properties in the X magnetic separator. The natural ferrite microparticles were synthesized by high energy ball milling in a Restch planetary ball mill with tungsten carbide balls and jars. A balltopowder ratio of 20:1, a milling rotation speed of 200 rpm and a milling time of 2, 4, and 6 h were used in the experiments. The choice of balltopowder ratioFine Iron Oxide Powder as a Raw Material of Soft Ferritesto obtain finer ferrite particles in a short ballmilling time, iron oxide (hematite, αFe2O3), which is the main raw material of ferrite accounting for about 70% of it by weight, has been demanded to have smaller particle aggregations. The iron oxide used for soft ferrite is generally manufactured by purifying waste pickling acid (ferrous
