In this work, the mill scale (MS) of hot rolling, a waste of steel processing, composed by a complex mixture of iron oxides, is transformed in a nanocrystalline powder containing only the hematite (α-Fe 2 O 3) phase.For that, the MS was dry-milled using a high-energy ball mill for 30 min and heat-treated up to 1200 °C for 25 min...α -Fe 2 O 3 nanocrystallines were prepared by direct transformation via high energy ball milling treatment for α -FeOOH powder. X-ray diffraction, Rietveld analysis, TEM, and vibrating sample magnetometer (VSM) are used to characterize the samples obtained after several milling times. Phase identification using Rietveld analysis showed that the goethite is …

Pure hematite particles of an average size of 14 nm were obtained after ball milling α-Fe 2 O 3 in a vertical vibrating mixer mill for 10 h. Möss and magnetization measurements indicate the existence of strong interparticle interactions that can be …...6 planetary ball mill). A ceramics (alumina) vessel of 500 cm3 volume and 10 alumina balls with 20 mm in diameter were used in this experiment. The rotating speed was main-tained constant at 200 rpm. The weight ratio of powder to balls was 1:5. The starting materials of graphite and hematite for milling were prepared as follows.

In the present study hematite ore of hardness 5.5–6.5, specific gravity 5.26 has been subjected to grinding tests in a ball mill. The experiments were conducted at three feed sizes (i. e., −10 ...In this work, a study on the dynamics of transformation from hematite (α-Fe 2 O 3 ) to magnetite (Fe 3 O 4 ) by following two solid-state reaction methods is carried out. One of the procedures consists of a thermal treatment under a 20% H 2 and 80% N 2 atmosphere at 375°C, whereas the second method involves a planetary ball mill to induce the transformation.
