The stable form of ferric oxide, hematite, designated α-Fe2O3, alpha iron oxide, has a rhombohedral structure, is nonmagnetic, and is the basis compound of red iron oxides. A metastable form of ferric oxide, denoted γ-Fe2O3, gamma iron oxide, is a defect spinel which has the magnetic property known as ferrimagnetism.

A grinder for increasing the bulk density of finely divided materials, using an energetic stream of driving fluid to act upon the particulate materials within a suitable grinding chamber. Particle sizes are reduced sufficiently by impact grinding to give a product of increased bulk density. The grinder is especially effective for the size reduction of hard abrasive materials.

The conversion of the 80% of initial hematite to amorphous phase during extended dry grinding by tumbling, planetary and vibratory mills, needs 4000, 8500 and 50,000 kJ/kg energy respectively. It was understood that vibratory mill introduces the minimum lattice strain and gives the largest crystallites when applying the same level of stress energy.
